Ischiogluteal bursitis is when the bursa located between the sit bone (ischial tuberosity) and the gluteal muscles becomes inflamed or irritated. This small, fluid-filled sac is meant to reduce friction between tissues, but when it’s aggravated, often from sitting too long or overuse, it can cause buttock pain, especially when sitting or stretching the hamstring.

An analogy…

Think of a bursa like a small water balloon cushioning your muscles from the bone. If you sit or press on it too much, it gets squashed and inflamed, like sitting too long on a bruise.

What causes ischiogluteal bursitis?

The ischial bursa lies between the ischial tuberosity (your “sit bone”) and the gluteus maximus muscle. It becomes inflamed from repetitive friction or direct pressure, especially with activities that involve prolonged sitting, running, or hamstring stretching. This leads to pain, swelling, and discomfort over the lower buttock.

What are the signs and symptoms of ischiogluteal bursitis?

• Pain in the lower buttock, near the sit bone
• Worsens with sitting, especially on hard surfaces
• Pain with walking, running, or stretching the hamstrings
• Tenderness over the ischial tuberosity
• Pain may feel deep and dull, and sometimes mimic hamstring origin tendonitis

What tests are used to diagnose on ischiogluteal bursitis?

Palpation: Direct pressure over the sit bone reproduces symptoms

Stretching tests: Pain when stretching the hamstrings

How long does ischiogluteal bursitis take to heal?

Mild cases can improve in 2 to 4 weeks with rest and modification. More stubborn or chronic cases may take 6 to 8 weeks. Severe or misdiagnosed cases may persist for several months if not properly managed.

How does ischiogluteal bursitis happen?

• Prolonged sitting on hard surfaces
• Direct trauma to the buttocks
• Tight hamstrings pulling on the bursa
• Weak glutes or poor posture when sitting or standing
• Running or long-distance walking with poor technique
• Overuse or sudden increase in physical activity

What treatment can help ischiogluteal bursitis?

• Rest from aggravating activities
• Ice application in early stages to reduce inflammation
• Manual therapy (e.g. massage, dry needling, soft tissue release)
• Postural correction and sitting modifications
• Stretching and strengthening exercises to address muscular imbalances

What exercises or stretches can I do for ischiogluteal bursitis?

• Gentle hamstring and glute stretches
• Glute activation exercises
• Core stability drills
• Hip and postural strengthening
