Coccydynia

Overview

Coccydynia is pain in the coccyx, commonly known as the tailbone. The coccyx is the small triangular bone at the very bottom of the spine. It helps support body weight when sitting and serves as an attachment point for muscles, tendons and ligaments in the pelvic area.

Tailbone pain can range from mild discomfort to severe pain that interferes with sitting, standing up from a chair, driving or daily activities. In many people, coccydynia improves with appropriate care and time. However, persistent or worsening pain should be assessed by a healthcare professional, especially if it follows an injury or is associated with other symptoms.

Symptoms

The main symptom of coccydynia is pain or tenderness at the base of the spine, just above the buttocks. The pain may be sharp, aching or pressure-like, and it may become more noticeable in certain positions or activities.

• Pain when sitting, especially on hard surfaces
• Pain when leaning backward while seated
• Discomfort when moving from sitting to standing
• Tenderness when the tailbone area is touched
• Pain during bowel movements in some cases
• Pain during sexual activity in some patients
• Local swelling or bruising after a fall or direct injury

Symptoms may develop suddenly after trauma or gradually without a clear cause. The intensity of pain does not always indicate the seriousness of the condition, so medical evaluation may be needed if symptoms persist.

Causes and Risk Factors

Coccydynia can occur when the coccyx or surrounding soft tissues become irritated, inflamed or injured. One of the most common causes is direct trauma, such as falling backward onto the buttocks. Repeated pressure on the tailbone can also contribute, especially in activities that involve prolonged sitting or cycling.

Possible causes and risk factors include:

• Falls or direct blows to the tailbone
• Childbirth-related strain or injury
• Prolonged sitting, particularly on hard or narrow surfaces
• Repetitive activities that put pressure on the coccyx
• Degenerative changes in the joints near the coccyx
• Increased or reduced body weight, which may affect sitting pressure and posture
• Previous lower back, pelvic or tailbone injuries

In some cases, no definite cause is found. Less commonly, infections, bone conditions or tumors can cause pain in the tailbone area. These possibilities are uncommon but may need to be considered when pain is severe, persistent or accompanied by warning signs.

Diagnosis

Diagnosis begins with a medical history and physical examination. The doctor may ask when the pain started, whether there was an injury, what movements make it worse, and whether there are symptoms such as fever, numbness, bowel or bladder changes, or unexplained weight loss.

During the examination, the doctor may gently assess the lower back, pelvis and tailbone area for tenderness, swelling, range of movement and signs of injury. In some cases, a rectal examination may be considered to assess coccyx movement or rule out other causes of pain.

Imaging may be requested when symptoms are persistent, severe, related to trauma, or not improving as expected. X-rays can help identify fractures, dislocations or abnormal alignment. In selected cases, more detailed imaging such as magnetic resonance imaging or computed tomography may be used to evaluate soft tissues, inflammation, infection or other underlying conditions.

Because pain near the tailbone can sometimes come from the lower spine, hips, pelvic organs or surrounding muscles, the diagnosis may include checking for other possible sources of discomfort.

Treatment Options

Treatment for coccydynia depends on the cause, severity and duration of symptoms. Most treatment plans begin with non-surgical approaches aimed at reducing pressure on the coccyx, improving comfort and supporting normal movement.

Conservative options may include activity modification, posture guidance, use of specially shaped cushions, and avoiding prolonged pressure on the tailbone when possible. Physiotherapy may be recommended to address muscle tension, pelvic floor involvement, posture, flexibility and movement patterns that may contribute to pain.

Healthcare professionals may also consider pain-relief strategies, depending on the patient’s overall health and medical history. These should be discussed with a doctor, particularly for people with chronic diseases, pregnancy, allergies or those taking other medicines.

If pain continues despite conservative care, other medical interventions may be considered. These can include image-guided injections around the coccyx or nearby nerve structures to reduce inflammation and pain. Such procedures are performed only after appropriate evaluation and when clinically suitable.

Surgery to remove part or all of the coccyx is rarely considered. It is usually reserved for carefully selected patients with long-lasting, disabling pain that has not improved with other treatments. The risks, benefits and recovery expectations should be discussed in detail with an orthopedic specialist or spine specialist.

When to See a Doctor

Medical evaluation is recommended if tailbone pain is severe, persists for more than a short period, or affects daily activities such as sitting, walking or sleeping. It is especially important to see a doctor after a fall, accident or childbirth-related injury if pain does not improve or is associated with swelling or bruising.

Seek prompt medical attention if tailbone pain is accompanied by fever, increasing redness or warmth, drainage from the skin, numbness or weakness in the legs, loss of bladder or bowel control, unexplained weight loss, or a history of cancer or serious infection. These signs do not always mean a serious condition is present, but they require timely assessment.

An orthopedic specialist can help identify the cause of coccydynia and recommend an appropriate treatment plan based on the patient’s symptoms, examination findings and overall health.
