Ischial Bursitis

Overview

Ischial bursitis is inflammation of a small fluid-filled cushion called a bursa. This bursa sits between the sitting bone and the hamstring muscles at the lower part of the buttock. When it becomes irritated, it can cause pain, tenderness, or a deep ache in the buttock, especially when you sit on a hard surface.

It is not one of the most common causes of buttock pain, but it does occur. Many people with buttock or sitting-bone pain turn out to have other causes, so a proper assessment matters.

It can affect anyone, but it is more likely in people who sit for long periods, cycle, run, do repeated hill or sprint work, or have tight hamstring muscles. It can also follow a direct injury or a change in walking pattern.

Symptoms

Common symptoms

• Pain or tenderness over the sitting bone at the lower buttock
• Pain that is worse when sitting on a hard chair, bench, or bicycle saddle
• A deep ache after long periods of sitting or after activities like running or cycling
• Pain that may ease when you stand up or sit on something soft
• Sometimes mild swelling or a feeling of fullness over the area

Symptoms in children

• This is uncommon in children. Buttock or hip pain in a child should be checked by a doctor because other causes are more likely.
• A child who is limping, refusing to walk, or has fever with hip or buttock pain needs prompt medical advice.

Symptoms in older adults

• Older adults may notice sitting-bone pain after falls, long periods of sitting, or changes in mobility.
• Thin skin, reduced padding over the sitting bone, and use of a walking aid can increase pressure in this area.
• Pain after a fall should be checked, especially if walking is difficult.

Causes

Main causes

• Prolonged pressure on the sitting bone from hard seats or long periods of sitting
• Repetitive friction or strain from cycling, running, jumping, or hill work
• A direct knock or fall onto the buttock
• Hamstring muscle tightness or Strain near the sitting bone
• Changes in walking pattern or pelvic position that increase pressure on the bursa

Risk factors

• Jobs or hobbies that involve long periods of sitting
• Cycling, running, or sports with repeated hamstring use
• Tight hamstrings or a sudden increase in training
• Previous injury to the buttock or hamstring
• Carrying extra body weight, which increases pressure on the sitting bone
• Diabetes or other conditions that may affect healing, though this is not the main cause

When to see a doctor

See a doctor urgently if:

• You cannot put weight on the leg or walking is severely limited
• You have fever, redness, warmth, or swelling over the buttock
• You have new numbness, tingling, or weakness in the leg
• You have loss of bladder or bowel control, numbness around the groin, or severe weakness in both legs — call emergency services
• Pain follows a fall or injury and is severe

Book a routine appointment if:

• Pain lasts more than a few weeks or keeps coming back
• Pain affects your work, sleep, sitting, or exercise
• Self-care is not helping
• You are limping or changing how you walk
• You have night pain or pain that is getting worse without a clear reason

Diagnosis

A doctor or physiotherapist will usually ask about your symptoms, sitting habits, activities, and any injuries. They will examine the buttock and hip, check how you walk, and press gently over the sitting bone. This is often enough to make a likely diagnosis.

Tests that may be done

• Usually no tests are needed
• Ultrasound scan may be used to look at the bursa and nearby tissues
• MRI scan may be arranged if the diagnosis is unclear or symptoms are unusual
• X-ray may be used to rule out a bone problem, especially after injury
• Blood tests may be considered if infection or another condition is suspected

What to expect at your appointment

The appointment is usually quick and does not require special preparation. You may be asked to lie on your side, stand, or walk a few steps so the clinician can examine the hip and buttock.

Treatment

Most people improve by reducing pressure on the sitting bone, changing activities that aggravate the area, and gradually rebuilding strength and flexibility. Treatment is usually simple and focused on calming irritation and preventing it from returning.

Self-care at home

• Avoid hard chairs and use a soft or padded seat when possible
• Take short breaks from sitting every 30 to 60 minutes
• Reduce running, cycling, jumping, or long sitting until pain settles; gentle walking is often fine
• Use a cold pack wrapped in a cloth for 10 to 15 minutes during a flare, or gentle heat for muscle tightness
• Try gentle hamstring stretches only if they do not increase pain
• Ask a pharmacist about over-the-counter pain relief that is suitable for you
• Return to activity gradually rather than all at once

Medical treatments

A doctor or physiotherapist may suggest physiotherapy to improve hamstring flexibility, hip strength, and walking pattern. They may also discuss injection therapy to reduce inflammation in the bursa, or other options depending on your examination and history. Any treatment plan should be tailored to you by a qualified healthcare professional.

When is surgery considered?

Surgery is uncommon for ischial bursitis. It may be considered only if symptoms are persistent, the diagnosis is confirmed, and other treatments have not helped. This would usually involve a specialist assessment first.

Living with this condition

You can often keep doing normal daily activities with some adjustments. Use a cushion for sitting, avoid long stretches on hard seats, and break up activities that put repeated pressure on the buttock.

Lifestyle tips

• Build a routine that mixes sitting, standing, and gentle movement
• Warm up before exercise and increase training gradually
• Keep hamstrings flexible with gentle stretches if advised
• Use a padded seat or cushion at work or when travelling
• Check your posture and seating setup with a physiotherapist or ergonomics adviser if pain keeps returning

Diet and exercise

A balanced diet and regular gentle activity support overall recovery. Exercise should start gently and build slowly. Avoid sudden increases in running, cycling, or hill work. Strength work for the hips and gentle hamstring flexibility can help, but stop any exercise that sharply increases pain.

Mental health and emotional wellbeing

Ongoing pain can be frustrating and may affect sleep, mood, work, and exercise. This is understandable. If pain is making you feel low or anxious, tell your doctor or physiotherapist. If you feel overwhelmed or have thoughts of harming yourself, contact your local crisis support service or emergency services right away.

Prevention

You cannot always prevent it, but you can lower the risk by avoiding long periods on hard seats, using padding, warming up before exercise, and increasing activity gradually. Keeping hamstrings flexible and hips strong may also help.

Vaccines

Vaccines are not used to prevent this condition.

Screening programmes

There is no screening test for ischial bursitis. See a clinician if you have ongoing sitting-bone or buttock pain.

Complications

If left untreated

• Pain may persist and make sitting uncomfortable
• Sleep, work, and exercise may be affected
• You may develop tightness or altered movement patterns around the hip and hamstring
• Rarely, persistent pain can become long-lasting and harder to settle

Long-term outlook

The outlook is usually good. Many people improve within weeks with self-care and activity changes, though some take longer. If pain continues, a healthcare professional can help refine the diagnosis and treatment plan.
