Hidradenitis Suppurativa: Painful Skin Boils and Flare Management

Hidradenitis suppurativa is a long-term inflammatory skin condition that causes painful lumps, boils, drainage, and scarring, most often in skin folds. With early diagnosis, flare planning, and individualized treatment, many people can reduce pain, limit new lesions, and protect quality of life.

Overview

Hidradenitis suppurativa, often shortened to HS, is a chronic inflammatory skin disease that can cause deep, painful lumps under the skin. These lumps may look like boils or abscesses and may break open, drain fluid, heal slowly, and return in the same area. HS most commonly affects areas with hair follicles and sweat glands where skin touches skin, including the armpits, groin, buttocks, inner thighs, and under the breasts.

Although HS can resemble an infection, it is not simply a hygiene problem and it is not contagious. The condition begins around hair follicles, where inflammation and blockage can lead to swelling, rupture, and deeper inflammation in nearby tissue. Bacteria may sometimes contribute to odor or secondary infection, but the underlying driver is an immune and inflammatory process.

HS can affect physical comfort, movement, sleep, clothing choices, intimacy, and emotional wellbeing. Some people have occasional mild flares, while others develop frequent painful lesions, tunnels under the skin, and scarring. A clear diagnosis and long-term management plan can help reduce flare frequency, control pain, and lower the chance of permanent skin changes.

Symptoms and Common Flare Patterns

Symptoms vary from person to person and may change over time. Early HS may begin as tender bumps, blackheads, or small pimple-like lesions in skin folds. During a flare, the area can become warm, swollen, and painful, and a lump may enlarge over days before draining or slowly settling.

Common HS signs include:

• Painful, deep nodules or boil-like lumps
• Abscesses that may drain pus or blood-stained fluid
• Blackheads or paired open comedones in affected areas
• Sinus tracts, also called tunnels, under the skin
• Thickened scars, rope-like scarring, or areas of darkened skin after healing
• Odor related to drainage, especially during active flares

Flares often occur in the same locations and may be triggered by friction, sweating, heat, stress, menstrual cycles, or irritation from shaving or tight clothing. Pain may be significant even when the skin change appears small on the surface, because HS inflammation can extend deeper than expected.

Doctors sometimes describe HS severity using stages. Mild disease may involve isolated nodules without scarring or tunnels. Moderate disease may include repeated abscesses and some scarring in several areas. More severe disease can include widespread or interconnected tunnels, chronic drainage, and thick scarring. Staging helps guide treatment choices, but each person’s symptoms and goals are equally important.

Causes and Risk Factors

The exact cause of hidradenitis suppurativa is not fully understood. Current medical understanding suggests that HS starts with blockage and inflammation around hair follicles. When a blocked follicle ruptures, the immune system reacts strongly, leading to painful inflammation, abscess formation, and sometimes tunnels and scars.

HS is not caused by unclean skin, and ordinary washing cannot prevent it. Genetics can play a role, as HS may run in families. The condition is also linked with immune system pathways, hormones, and metabolic factors. It often begins after puberty and may flare around menstrual periods in some women, suggesting that hormonal influences can be important.

Several factors can increase the risk of HS or make flares worse in some people. These include smoking, excess body weight, skin friction, sweating, and a family history of HS. People with HS may also have related health conditions such as acne, pilonidal disease, inflammatory bowel disease, metabolic syndrome, depression, or anxiety, although not everyone develops these associations.

Understanding risk factors should not create blame. HS is a medical condition, and lifestyle changes alone do not cure it. However, identifying personal triggers and addressing modifiable factors can support medical treatment and may reduce the burden of flares.

Diagnosis

Hidradenitis suppurativa is usually diagnosed by a dermatologist or experienced clinician through medical history and skin examination. There is no single blood test that confirms HS. The diagnosis is based on the type of lesions, their location, and the pattern of recurrence over time.

A doctor may ask when the lumps began, how often they return, whether they drain, which areas are affected, and whether there is a family history of similar symptoms. The clinician will also look for signs such as tunnels, scarring, recurring abscesses, and blackheads in typical HS areas. Photographs taken over time may help document flare patterns and treatment response.

Tests may be used when another condition is possible or when complications are suspected. A swab or culture may be taken if there are signs of secondary infection. Blood tests may be recommended to assess inflammation, anemia, diabetes risk, or suitability for certain medicines. Ultrasound imaging can sometimes help identify tunnels or fluid collections beneath the skin, especially before procedures.

Conditions that can mimic HS include ordinary boils, folliculitis, infected cysts, pilonidal disease, Crohn-related skin disease, sexually transmitted infections, and certain inflammatory skin disorders. Correct diagnosis matters because repeated short courses of treatment for simple infection may not address the long-term inflammatory nature of HS.

Treatment Options

Treatment for hidradenitis suppurativa is individualized. The goals are to reduce pain, shorten flares, prevent new lesions, control drainage and odor, protect mobility, and prevent scarring or tunnels. A treatment plan may combine daily skin care, medicines, procedures, and support for pain and emotional wellbeing.

For mild or early HS, doctors may recommend antiseptic washes, topical antibiotics, anti-inflammatory skin treatments, and strategies to reduce friction. Oral antibiotics may be used for their anti-inflammatory effect as well as to treat bacterial overgrowth when appropriate. Pain control can include non-prescription or prescription options, warm compresses, and treatment of active abscesses when needed.

For moderate to severe HS, additional treatments may be considered. These can include longer courses of anti-inflammatory antibiotics, hormonal therapies for suitable patients, retinoids in selected cases, or biologic medicines that target specific immune pathways. Biologic therapy requires medical assessment, monitoring, and screening for infections before and during treatment.

Procedures may be helpful when a lesion is very painful, recurrent, or has formed tunnels. Simple incision and drainage may relieve pressure from an acute abscess but often does not prevent recurrence. Other approaches, such as deroofing, laser treatment, limited excision, or wider surgical removal, may be recommended for persistent tunnels or scarred areas. The best option depends on disease stage, location, healing considerations, and the person’s overall health.

Flare Management, Prevention, and Self-care

Self-care cannot replace medical treatment, but it can reduce irritation and make flares easier to manage. Gentle cleansing, avoiding harsh scrubbing, and keeping affected areas as dry and comfortable as possible may help. People with HS often benefit from loose, breathable clothing and underwear that reduces rubbing in the groin, underarm, or breast area.

During a flare, warm compresses may ease discomfort and encourage natural drainage. Lesions should not be squeezed or cut at home, because this can worsen inflammation, increase pain, and raise the risk of infection or scarring. If drainage occurs, clean absorbent dressings can protect clothing and skin; a clinician or wound care nurse can advise on suitable dressings for frequent drainage.

Practical strategies that may help reduce flare triggers include:

• Stopping smoking with medical support, if relevant
• Working toward a sustainable weight plan when excess weight contributes to friction
• Choosing friction-reducing clothing and avoiding tight seams
• Managing heat and sweating where possible
• Using careful hair removal methods and avoiding shaving irritated skin
• Tracking menstrual, stress, food, or activity patterns that seem linked to flares

Diet changes are not a proven cure for HS, and no single diet works for everyone. Some people report fewer flares after reducing certain foods, but changes should be balanced and medically safe. If food triggers are suspected, a dietitian or doctor can help avoid unnecessary restriction, especially for people with diabetes, digestive conditions, pregnancy, or other health needs.

Living With HS and Emotional Wellbeing

HS can be emotionally challenging because symptoms may be painful, visible, recurrent, and sometimes associated with drainage or odor. People may feel embarrassed, avoid social events, or delay seeking help. Reassurance is important: HS is a recognized medical condition, and compassionate care is available.

Quality of life support is part of good HS care. Pain management, wound care guidance, mental health support, and practical advice about clothing, work, exercise, and intimacy can all be helpful. People with HS may benefit from discussing anxiety, low mood, sleep disruption, or body image concerns with a doctor, psychologist, or counselor.

Good communication with the healthcare team can improve treatment success. Keeping a flare diary, noting triggers, taking photos when appropriate, and reporting how symptoms affect daily life can help the doctor adjust treatment. Because HS can change over time, treatment plans often need review rather than a one-time prescription.

When to See a Doctor

A medical evaluation is recommended for painful boils or lumps that return in the same areas, especially the armpits, groin, buttocks, inner thighs, or under the breasts. Early dermatology care is especially helpful when lesions drain, leave scars, form tunnels, or interfere with walking, sitting, working, sleep, or relationships.

Prompt medical attention is important if there is spreading redness, fever, rapidly increasing pain, or a person feels generally unwell, as these may indicate infection or another urgent problem. A doctor should also review lesions that do not heal, recurrent abscesses after antibiotics, or symptoms near the anus or genitals where other conditions may need to be excluded.

Specialist care may include dermatology, surgery, wound care, pain management, endocrinology, gastroenterology, nutrition, and mental health support when needed. Acibadem International’s multidisciplinary specialists and JCI-accredited hospitals diagnose and treat hidradenitis suppurativa for international patients, with care planned according to disease severity and individual needs.

Frequently asked questions

Is hidradenitis suppurativa contagious?

No. Hidradenitis suppurativa is not contagious and cannot be spread by touching, sharing towels, or close contact. It is an inflammatory condition involving hair follicles and the immune system, although bacteria may sometimes be present in draining lesions.

Is HS caused by poor hygiene?

No. HS is not caused by being unclean, and excessive washing or scrubbing may actually irritate the skin. Gentle cleansing can support comfort and reduce odor, but medical treatment is often needed to control inflammation.

Can hidradenitis suppurativa be cured?

There is currently no guaranteed permanent cure for HS, but many people achieve better control with the right treatment plan. Early diagnosis, trigger management, medicines, and selected procedures can reduce flares and prevent complications.

What should a person do during a painful HS flare?

Warm compresses, loose clothing, clean dressings, and doctor-approved pain relief may help during a flare. Lesions should not be squeezed or opened at home. If pain is severe, drainage is heavy, or there are signs of infection, medical care is recommended.

Do antibiotics always mean HS is an infection?

Not always. Antibiotics are often used in HS because they can reduce inflammation as well as treat bacterial overgrowth when present. A doctor will decide whether topical, oral, or other treatments are appropriate based on severity and response.

Can lifestyle changes help HS?

Lifestyle measures may help reduce triggers for some people, especially stopping smoking, reducing friction, managing sweating, and addressing excess weight when relevant. These steps are supportive, not a replacement for medical care. HS is a medical condition and should be managed without blame.

When is surgery considered for hidradenitis suppurativa?

Surgery or minor procedures may be considered when lesions repeatedly return, form tunnels, scar, or do not respond well to medicines. Options range from deroofing a tunnel to removing a persistently affected area. The choice depends on location, severity, healing needs, and the patient’s overall treatment plan.
