Exercise After Shock Wave Therapy: Why Loading the Tendon Matters Once Soreness Settles

The session lasted less than ten minutes. Now she is sitting in the car with her shoe off, pressing a thumb into a heel that feels warm, oddly buzzy and a little bruised, reading the printed sheet the physiotherapist handed her. It lists calf raises and a towel stretch. It does not say when. Tonight? Tomorrow? Does exercise after shockwave therapy undo the treatment she just paid attention to for weeks?

That uncertainty is common, and it hides a bigger question. People tend to think of the machine as the treatment and the exercises as homework. For a tendon that has been sore for months, the evidence points the other way round. The pressure pulses are a short, sharp nudge. The loading program is the long conversation that persuades the tissue to rebuild.

This explainer walks through what actually happens in the tendon, what the first two days usually feel like, how to reintroduce load without flaring things up, and the signs that mean you should stop and call your doctor.

What shockwave therapy actually does to a sore tendon

Extracorporeal shock wave therapy, usually shortened to ESWT or just shockwave, is a treatment in which a handheld applicator sends pressure pulses through the skin into a painful tendon, ligament or fascia. Extracorporeal simply means the energy is generated outside the body. Two broad designs exist. Focused devices concentrate energy at a set depth; radial devices spread a pressure wave from the skin surface outward. Your clinician chooses based on the target tissue.

What the pulses do is still debated, and it is worth being honest about that. Laboratory and animal work suggests several overlapping effects: a controlled mechanical stimulus that provokes tiny areas of irritation and a fresh repair response, increased local blood flow and new small vessel growth, release of growth factors involved in collagen production, and a dampening of pain-signalling fibres in the area. In calcific tendinopathy of the shoulder, the pulses can also fragment calcium deposits so the body clears them more easily.

The clinical evidence is mixed rather than settled. Mayo Clinic notes that for plantar fasciitis, shockwave has shown promising results in some studies but has not been shown to be consistently effective, and it is generally reserved for people whose heel pain has not responded to more conservative care. Guideline bodies in the UK reviewed the same body of evidence and reached a similar conclusion: the procedure appears safe, while the quality of evidence for benefit is limited and varies by site.

None of that makes shockwave pointless. It means the pulses are a stimulus, not a repair. The tendon still has to be shown, week after week, what it is expected to tolerate. That is the job of load.

Why exercise after shockwave therapy matters more than the shocks

Tendinopathy is the umbrella term for a tendon that has become painful and thickened, usually after months of being asked to do more than it could adapt to. Under a microscope, the neat parallel collagen fibres are disorganised, there are more cells and more water than usual, and small blood vessels and nerves have crept in. That is not classic inflammation, which is why the older word tendonitis has fallen out of favour among specialists.

Tendons are living tissue that remodel in response to force. Cells called tenocytes sense stretch and compression and respond by laying down and aligning new collagen. This process, mechanotransduction, is the reason a tendon that is loaded progressively gets stiffer and stronger, while one that is rested for months gets thinner and less able to store energy. Rest feels protective. In chronic tendon pain it often does the opposite.

This is where the order of operations matters. Nearly every trial that reported benefit from shockwave delivered it alongside a structured exercise program, most commonly stretching and calf or forearm strengthening. When the pulses are studied on their own, results are less convincing. The most reasonable reading of the evidence is that shockwave may reduce pain and make loading easier to tolerate, and loading then does the slow work of rebuilding capacity.

If you take one opinion from this article, take this one: the printed sheet of exercises is not the optional part. Missing sessions on the couch is the same as skipping the treatment. The team who arranged your shockwave almost certainly sees it this way too, which is why the exercises were handed to you before you left the room.

Who is usually offered shockwave, and who is usually asked to wait

Shockwave is typically considered for chronic tendon and fascia problems that have persisted despite first-line care: rest from the aggravating activity, footwear or workload changes, and a properly progressed exercise program. Common targets include plantar fasciitis (pain in the thick band of tissue under the foot), Achilles tendinopathy, lateral elbow tendinopathy (tennis elbow), pain at the side of the hip from the gluteal tendons, and calcific tendinopathy of the rotator cuff in the shoulder. NHS guidance on plantar fasciitis and tendonitis positions procedures like this after self-management and physiotherapy have been tried.

Some people are usually asked to wait, or are steered elsewhere, because the pulses could cause harm or the cause of pain is different:

• Pregnancy, particularly when the target is near the trunk or pelvis.
• Bleeding disorders or blood-thinning medicines, because the pulses can bruise deep tissue; your prescriber decides how to handle this, and you should never adjust a medicine yourself.
• Infection, an open wound or a skin condition over the treatment area.
• A known or suspected tumour in the region.
• Children and teenagers whose growth plates are still open near the site.
• A recent corticosteroid injection into the same area, since both treatments stress the tendon.
• A suspected tendon tear rather than tendinopathy, which needs a different plan.
• Certain implanted electrical devices near the target, depending on the equipment.

A careful assessment also screens for conditions that mimic tendon pain. Heel pain from a stress fracture, nerve entrapment or an inflammatory arthritis should not be treated as plantar fasciitis. The decision to proceed, and how many sessions to plan, rests with the treating team after that assessment.

What the first 48 hours after a session usually feel like

The applicator is uncomfortable while it is on the skin, and most people describe the treated spot afterwards as tender, warm and slightly swollen, as though it has been firmly massaged. Some notice pinpoint redness or a light bruise. A tingling or briefly numb patch is also common and generally fades over hours. This soreness is expected, and it is one reason clinics often schedule sessions in the afternoon or before a rest day.

Ordinary movement is not off the table in this window. Walking, climbing stairs and normal work are usually fine unless your team says otherwise, and staying gently mobile helps the ache settle. What most programs pause is the deliberate strengthening, particularly the heavier or more explosive drills, until the tissue no longer feels sensitive to pressure. For many people that is a matter of a day or two, but it varies with the site, the energy used and your own sensitivity, so treat your clinician’s instruction as the reference, not the average.

Two practical points come up repeatedly. First, the treated area can feel better than usual for a short while because the pulses temporarily quieten pain fibres. That relief is real but not a signal that the tendon is suddenly stronger; the urge to test it with a long run or a hard gym session is exactly what sabotages the week. Second, some teams ask you not to ice the spot or take anti-inflammatory medicines for a period around the session, on the reasoning that the local response may be part of how the treatment works. The evidence for that instruction is thin either way, which is why you should follow what your own team advises rather than a forum thread.

What not to do after shockwave therapy

The list of things to avoid is shorter than most people expect, and it is bracketed by two opposite mistakes: doing far too much, and doing nothing at all.

• Do not test the tendon on day one. A hill run, a heavy calf raise session or a long day in flat shoes on concrete stacks a fresh load onto tissue that has just been provoked on purpose.
• Do not stop moving entirely. Bed rest or a week off your feet lets the tendon deload, which is the opposite of what a chronic tendon needs. Walking and light daily activity are almost always encouraged.
• Do not self-prescribe anti-inflammatories. Non-steroidal anti-inflammatory drugs work by blocking prostaglandins, chemical messengers involved in pain and the local tissue response. Whether that blunts the effect of shockwave is uncertain, so ask your prescriber rather than reaching for the cabinet.
• Do not add a second new intervention the same week. A new insole, a different running shoe and a fresh stretching routine all at once makes it impossible to know what helped and what hurt.
• Do not skip the home program between sessions. The pulses are spaced out; the loading is what fills the gap.
• Do not push through pain that is climbing day after day. A tolerable ache that settles overnight is one thing; pain that is worse each morning is a message.
• Do not ignore skin changes. Blistering, spreading redness or a large expanding bruise is not a normal response and should be reported.

A common thread runs through these: shockwave changes the tendon’s sensitivity for a short period, and decisions made during that window either build on the stimulus or waste it. Keeping the week around a session boring, consistent and well slept is not glamorous, but it is what the evidence rewards.

When can you start exercise after shockwave therapy? A typical timeline

There is no single protocol, and any clinic that promises one is simplifying. What follows is the shape most physiotherapy-led programs take. The specific days are set by your team.

Session day. Normal walking and daily activity. Many programs ask you to skip formal strengthening and any impact exercise for the rest of the day. Gentle range-of-motion movement, such as slowly pumping the ankle or opening and closing the hand, is usually fine and can ease stiffness.

Once the soreness settles. Isometric exercises typically return first. An isometric contraction is one where the muscle works hard but the joint does not move, such as standing on tiptoe and holding still. These are well tolerated by irritable tendons and can reduce pain in the short term, which makes them a sensible first step back.

Over the following days. Most people resume the strengthening they were doing before the session at the same level, not a higher one. The temptation to skip ahead because the tendon feels better should be resisted; progress is decided by how the tissue responds over 24 hours, not by how it feels in the moment.

Between sessions. The loading program continues throughout the course. Skipping exercises because another session is booked misunderstands how the two fit together.

After the final session. This is where the real progression happens: heavier resistance, then eccentric and eventually energy-storage work such as hopping, if your goals require it. Tendon remodelling is slow. Mayo Clinic notes that most people with plantar fasciitis improve over several months with conservative treatment, and the same patience applies to other tendons. A course of shockwave does not compress that timeline into a fortnight.

Which exercises load a tendon well, and in what order

Tendon rehabilitation is less about picking the perfect exercise and more about matching the type of load to how irritable the tendon is right now. The broad categories below appear in most evidence-based programs. Sets, repetitions and resistance are chosen by your physiotherapist and progressed on the basis of your response; they are not listed here because a number that suits one person can flare another.

Type of loading	What it looks like	Usually introduced when	Why it is used
Isometric	Holding a position under load without movement: a still heel raise, a wall sit, holding a wrist extended against a light weight	Early, including in the days after a session	Well tolerated by sensitive tendons; can give short-term pain relief; keeps the tissue working
Heavy slow resistance	Slow, controlled lifting and lowering with meaningful resistance, such as a slow calf raise on a step	Once daily pain is manageable and settles overnight	Drives collagen synthesis and stiffness; builds muscle so the tendon is better protected
Eccentric	Emphasising the lowering phase, such as rising on two feet then lowering slowly on one	Mid-program	Long-standing evidence for Achilles and elbow tendinopathy; loads the tendon through a lengthening range
Energy storage and release	Hopping, skipping, jumping, sprint drills	Late, and only if the sport demands it	Prepares the tendon for the rapid stretch-and-recoil of running and jumping

Site-specific examples help make this concrete. For plantar fasciitis, a heel raise performed with a rolled towel under the toes loads the fascia along with the calf, and a seated stretch of the sole is often added. For the Achilles, heel drops off a step are the classic eccentric drill. For tennis elbow, slow wrist extension against light resistance targets the forearm tendons. Hip tendon pain usually starts with bridges and side-lying leg work before progressing to single-leg standing tasks. The NHS and MedlinePlus both stress that these programs should be taught and progressed by a professional rather than copied from a video.

How hard is too hard? Using pain as your guide

People who have hurt for months tend to treat every twinge as damage. Tendon rehabilitation asks you to unlearn that, within limits. Some discomfort during and after loading is expected, and a program that produces none is probably too light to change the tissue.

Many physiotherapists use a simple monitoring convention drawn from tendinopathy rehabilitation research. Pain during the exercise is acceptable if it stays at a level you would call tolerable rather than sharp or alarming. More important is what happens afterwards: the ache should ease by the next morning and not be worse than the day before. Morning stiffness and the first few steps out of bed are useful barometers for the Achilles and plantar fascia because they respond to the previous day’s total load. This is a rule of thumb rather than a guideline figure, and your team may set the threshold differently.

Read the pattern over days, not hours. A tendon that is a little sore after a session but calm by breakfast is coping. One that is progressively more painful each morning across a week is telling you the load has outpaced adaptation, and the right response is to hold or step back a level, not to stop completely. Sharp pain, a sudden loss of strength or a feeling of giving way is a different category and covered in the red-flag section below.

Life load counts too. A long shift on hard floors, a weekend of gardening or a change to flat, unsupportive shoes adds to the tendon’s daily total just as surely as a gym session. If a flare appears out of nowhere, look at the whole week before blaming the exercises.

Finally, keep a short log. Two lines a day recording what you did and how the tendon felt the next morning gives your physiotherapist far better information than memory, and it makes progression decisions evidence-based rather than hopeful.

Running after shockwave therapy: rebuilding impact step by step

Runners ask the timing question more urgently than anyone, because running is the activity that most often caused the problem and the one they most want back. The honest answer is that the return depends on the tendon, not the calendar, and shockwave does not shorten the ladder; at best it makes the rungs less painful to climb.

A typical return-to-running progression looks like this. Brisk walking comes first, on flat, forgiving surfaces. Once walking is comfortable and the tendon is quiet the next morning, short intervals of easy jogging are mixed into walking. Only when continuous easy running is tolerated do hills and faster efforts return, and usually one at a time so the cause of any flare is obvious. Each step up is judged by the 24-hour response described above.

Change one variable at a time. Distance, pace, gradient, surface and footwear all load the Achilles and plantar fascia differently. Increasing two together is the most common way people undo weeks of progress in a single Saturday.

Cross-training keeps fitness without impact. Cycling, deep-water running and rowing maintain cardiovascular capacity while the tendon adapts. The CDC recommends adults accumulate at least 150 minutes of moderate-intensity activity a week plus muscle-strengthening on two or more days; for most people in tendon rehabilitation, meeting that target through lower-impact options while the running ladder progresses is realistic and worthwhile.

Watch for compensation. A runner protecting a sore heel often shortens stride on one side or lands harder on the other, which can shift the problem rather than solve it. If a new ache appears in the opposite leg, knee or hip during your return, mention it at the next appointment.

Racing is a separate decision. Training tolerance builds gradually; race-day effort is a spike. Discuss any event on your calendar with your team well before you commit to it.

How to tell if shockwave therapy is working

Because the tendon changes slowly and pain fluctuates day to day, it is easy to misjudge progress in either direction. A good day is not proof of success; a bad day is not proof of failure. Look instead for trends across two to four weeks.

The signals clinicians tend to watch are functional. Morning first-step pain that used to last minutes now lasts moments. You can stand for a full shift, or walk to the shops, with less thought about the heel. The strengthening exercises can be progressed to a heavier level without the tendon protesting the next day. Pain during the exercises themselves may not change much for a while; tolerance afterwards usually improves first. Many physiotherapists track this with a short questionnaire scored at intervals, which turns a vague sense of better into a number you can compare.

What the evidence does not support is expecting a visible change on ultrasound to match how you feel. Tendon appearance on imaging often lags symptoms by months and sometimes never normalises even when pain resolves. Improvement is measured by what you can do, not by what the scan shows.

Be equally honest about non-response. Shockwave does not help everyone. Mayo Clinic describes its effectiveness for plantar fasciitis as inconsistent across studies, and trials in other tendons show a similar spread. If several sessions and a faithfully performed loading program have not shifted the trend, the answer is not necessarily more of the same. Your team may revisit the diagnosis, adjust the exercise plan, or discuss other options, which for stubborn cases range from different injection approaches to, rarely, surgery. Each carries its own risks and none is guaranteed to help, so the choice sits with you and the clinicians who know your case.

Shockwave therapy recovery time: what weeks 4 to 12 and beyond usually look like

Ask a room of people who have finished a course of shockwave when they felt different and the answers scatter widely. Some report relief within the first couple of weeks, some describe a slow drift toward better over a season, and some notice no change at all. That scatter is the evidence, not a flaw in it.

A few anchors help set expectations. The NHS notes that mild, recent tendonitis often settles within two to three weeks with self-care, but the tendons that reach a shockwave clinic are rarely mild or recent; they have usually been sore for months. Mayo Clinic describes recovery from plantar fasciitis with conservative treatment as taking several months, and Achilles tendinopathy follows a similar arc. Tissue remodelling, the laying down and realigning of collagen, runs on a timetable of months rather than weeks, whatever is done to kick-start it.

In practice, the first month after a course tends to be about consistency: performing the loading program, monitoring the 24-hour response and keeping daily life load steady. Weeks four to twelve are where progression usually happens, with heavier resistance, then eccentric work, then sport-specific drills if needed. Setbacks in this window are common and are usually a load-management problem rather than a sign the treatment failed. Beyond three months, the goal shifts to maintenance: tendons that have been painful once are vulnerable to returning to old habits, and many physiotherapists suggest keeping a reduced version of the strengthening work going long term.

None of these ranges is a promise. They are the typical shape described in mainstream patient guidance, and your own course may be shorter or longer. What the ranges do offer is a reason not to judge the outcome after ten days.

What people often get wrong about shockwave and tendons

Myths cluster around this treatment, partly because the machine looks impressive and partly because the biology is genuinely complicated. Six deserve a plain correction.

Shockwave breaks up muscle knots. A knot, or trigger point, is a tender, tight-feeling band in a muscle. Whether it is a discrete physical structure is itself debated, and the evidence that pressure pulses dissolve anything in muscle is weak. Some clinics use shockwave for muscular pain; the research base there is thinner than for tendons, and any relief is more plausibly explained by short-term effects on pain fibres than by mechanical disruption.

Shockwave dissolves scar tissue. Tendinopathy is disorganised collagen, not scar tissue in the surgical sense, and the pulses do not melt it away. They may prompt remodelling that loading then completes.

Rest until it stops hurting, then exercise. Chronic tendons rarely stop hurting with rest, and the tissue deconditions while you wait. Load within tolerance is the treatment.

If it hurts during the session, it is working. Discomfort is a side effect of the energy delivered, not a measure of benefit.

More sessions are always better. Higher totals have not been shown to be reliably superior, and each session adds a period of soreness that interrupts loading. Your team chooses the course length.

Shockwave heals tendonitis on its own. The trials that showed benefit paired it with exercise. Where it appears to help, it helps as an adjunct. Presenting it as a stand-alone fix overstates what the evidence supports, and the NHS and Mayo Clinic both place it after, not instead of, a proper exercise program.

Painkillers, anti-inflammatories and injections: how they interact with the loading plan

Medicines come up in three ways around shockwave, and each has a mechanism worth understanding before a conversation with your prescriber. Nothing here is a recommendation to start, stop or change anything.

Non-steroidal anti-inflammatory drugs. These block cyclo-oxygenase enzymes and reduce prostaglandins, chemical messengers that amplify pain and drive parts of the local tissue response. They are widely used for tendon pain, and MedlinePlus lists them among standard options for tendinitis. Some clinicians ask people to avoid them for a period around shockwave sessions on the theory that the treatment relies on a local response the drugs might dampen. The evidence for that concern is limited and indirect. Ask your prescribing clinician what they advise and follow it; do not stop a medicine you take for another reason without checking.

Simple analgesics. Paracetamol, known as acetaminophen in the US, works through a different pathway and does not carry the same theoretical concern. It also does not change the tendon. Whether it fits your plan is again your prescriber’s call.

Corticosteroid injections. These deliver a potent anti-inflammatory directly around the tendon and can reduce pain in the short term. Mayo Clinic notes that repeated injections are generally avoided because they may weaken the tendon or, for the plantar fascia, contribute to rupture. Because both steroid and shockwave stress the tissue, teams usually space them apart or choose one path. Other injection approaches, such as platelet-rich plasma, are sometimes offered; the evidence for them is mixed and they are not consistently better than a well-run exercise program.

The common thread is that medicines manage symptoms while loading changes the tendon. Pain relief that lets you complete your exercises is useful; pain relief that lets you ignore a tendon’s limits is not.

Questions to ask your care team before and after a session

A good clinic will welcome these questions, and the answers will tell you as much about the quality of your plan as about the treatment itself. Take notes; post-session soreness is not conducive to remembering detail.

• What exactly are we treating, and how confident are you in the diagnosis? Has anything else that can mimic this pain been ruled out?
• What has the evidence shown for shockwave at this particular site, and what would you expect if we did the exercise program alone?
• How many sessions are you planning, how far apart, and what would make you stop early or extend the course?
• Which of my current exercises should pause after a session, which can continue, and when do I resume the full program?
• What level of pain during and after exercise do you consider acceptable, and how should I judge whether to progress or hold?
• Are there activities, footwear or work tasks you want me to change for the duration?
• Should I avoid ice, heat or any of my usual medicines around sessions? If so, for how long, and who do I check with about my prescriptions?
• How will we measure progress, and at what point would we reconsider the plan if it is not helping?
• What side effects are expected, and which ones mean I should contact you straight away?
• If I want to return to running or a specific sport, what does the ladder back look like and who guides it?
• What are the alternatives if this does not work, including doing nothing further, and what are the risks of each?

Notice that most of these are about the exercise plan rather than the machine. That reflects where the leverage is. A clinician who can answer the loading questions in detail is offering you the part of the treatment that the evidence most consistently supports.

When to call your doctor

Expected effects of shockwave are local and short-lived: tenderness, mild swelling, a small bruise, brief tingling. The following are not expected and need prompt medical attention, either from the team that treated you or, for the most urgent, emergency services.

• A sudden snap, pop or tearing sensation in the tendon, especially the Achilles, followed by weakness, inability to push off the foot or stand on tiptoe, or a visible gap or change in shape. This can indicate a rupture and needs same-day assessment.
• Rapidly increasing swelling, redness, heat or spreading discolouration at the treated site, particularly with fever or feeling unwell, which could signal infection or significant bleeding.
• Numbness, pins and needles or weakness that persists beyond a few hours or spreads away from the treatment area.
• Blistering, skin breakdown or a large expanding bruise over the site.
• Pain that is escalating day after day rather than settling, or new pain in a different location such as the bone or joint.
• Calf pain, swelling or warmth in one leg, or sudden breathlessness or chest pain, which are warning signs of a blood clot and warrant emergency care regardless of the cause.
• Any symptom your team specifically told you to report.

Short of an emergency, use your judgment about the trend. If the tendon is clearly worse a week after a session than it was before, if you cannot perform exercises you managed comfortably a fortnight ago, or if you are unsure whether what you feel is normal, call rather than wait for the next scheduled appointment. Clinics expect these calls. Every decision about continuing, pausing or changing course, including whether to have further sessions or move to a different approach, belongs with your treating team, informed by what you report.

Frequently asked questions

What not to do after shockwave therapy?

Avoid testing the tendon with high-impact or heavy strengthening on the day of treatment, but do not stop moving either; walking and normal daily activity are usually encouraged. Do not self-prescribe anti-inflammatories or apply ice without asking your team, do not introduce several new changes such as insoles and shoes in the same week, and do not push through pain that is worse each morning. Report blistering, spreading redness or a large bruise.

How to tell if shockwave therapy is working?

Look for functional trends over two to four weeks rather than single good or bad days: shorter first-step pain in the morning, more tolerance for standing or walking, and the ability to progress your strengthening exercises without a next-day flare. Pain during exercise often changes later than tolerance afterwards. Imaging appearance lags symptoms by months and is not a useful yardstick. If the trend has not shifted after the planned course, your team may revisit the diagnosis or plan.

Does shockwave therapy break up muscle knots?

The evidence does not support that idea. A muscle knot, or trigger point, is a tender tight band whose physical nature is itself debated, and studies of shockwave in muscular pain are fewer and weaker than in tendons. Any short-term relief is more plausibly explained by temporary effects on pain-signalling fibres than by mechanical disruption of tissue. For tendon problems, the treatment is best understood as a stimulus that loading then builds on.

Can shockwaves heal tendonitis?

Not on their own, and the evidence is mixed even as an add-on. Mayo Clinic describes shockwave for plantar fasciitis as promising in some studies but not consistently effective, and trials in other tendons show a similar spread. Where benefit is seen, it is almost always alongside a progressive exercise program, which drives the collagen remodelling that restores tendon capacity. Most chronic tendon pain improves over months, and shockwave does not shorten that biology.

How soon can I exercise after shockwave therapy?

Normal walking and daily activity are usually fine the same day. Structured strengthening typically pauses until the treated area is no longer tender to pressure, which for many people is a day or two, though this varies by site and individual. Isometric holds are usually the first exercises reintroduced, followed by a return to your previous level of loading rather than a jump ahead. Your treating team sets the exact timing for your case.

What is a realistic shockwave therapy recovery time?

Think in months, not weeks. The NHS notes mild recent tendonitis often settles in two to three weeks with self-care, but tendons treated with shockwave have usually been painful for far longer, and Mayo Clinic describes conservative recovery from plantar fasciitis as taking several months. The first month after a course is typically about consistency, weeks four to twelve about progression, and beyond that about maintaining strength. These are typical ranges from patient guidance, not promises.

Is running after shockwave therapy safe?

It can be, provided impact is rebuilt in steps rather than resumed at previous volume. Most programs move from brisk walking to walk-run intervals to continuous easy running, adding hills and speed last, with each step judged by how the tendon feels the next morning. Change one variable at a time, keep fitness with cycling or pool work meanwhile, and discuss any race plans with your team well in advance. Shockwave does not shorten this ladder.

Should I avoid ice or anti-inflammatories after a session?

Some clinicians ask people to avoid both for a period around sessions on the theory that the local tissue response is part of how shockwave works and could be dampened. The evidence for this is limited and indirect. Non-steroidal anti-inflammatory drugs block prostaglandins involved in pain and tissue response; paracetamol works differently. Follow your own team’s instructions, and never stop a medicine prescribed for another reason without checking with the prescriber.

Why does my tendon feel better right after shockwave and worse two days later?

The pulses temporarily quieten pain-signalling fibres, so the area can feel unusually good for a short window, while the deliberate irritation they cause produces soreness that peaks over the following day or two. That pattern is common and expected. It becomes a problem only when the good window tempts people into a heavy session that then adds a real overload flare on top. Judge the tendon by its next-morning response across the week, not by the immediate aftermath.

What are the alternatives if shockwave and exercise do not help?

Your team would usually first re-examine the diagnosis, since stress fractures, nerve entrapment and inflammatory conditions can mimic tendon pain, and then review whether the loading program was progressed appropriately. Beyond that, options range from adjusting footwear or activity, to different injection approaches, to surgery in a small minority of stubborn cases. Each has its own risks and none is guaranteed. The decision sits with you and the clinicians who know your case.
