Ischiogluteal bursitis causes pain just below the buttock, typically worse when sitting. It develops when the bursa between the hamstring tendon and sit bone becomes inflamed, often due to pressure or friction.
Symptoms
- Pain directly under the buttock at the ischial tuberosity (sit bone)
- Pain worse when sitting, especially on hard surfaces
- Local tenderness when pressing on the area
- Pain when stretching the hamstring
- Gradual onset of symptoms
Which is it – bursitis or tendinopathy?
- Pain mainly when sitting – likely Ischiogluteal Bursitis
- Pain worse with running or exercise – more likely Proximal Hamstring Tendinopathy
- Sudden sharp pain during activity – probably an upper hamstring tendon strain
- Pain with both sitting and activity – possible combination of both bursitis and tendinopathy
What is Ischiogluteal Bursitis?
Ischiogluteal Bursitis is inflammation of the bursa located between the hamstring tendon and the ischial tuberosity (sit bone).
The bursa normally reduces friction between structures. When irritated, it becomes inflamed and painful, particularly when compressed during sitting.
Causes
- Prolonged sitting, especially on hard surfaces
- Repetitive friction between tendon and bone
- Overuse from running or training
- Direct pressure or trauma
- Co-existing Proximal Hamstring Tendinopathy
Why does it hurt when I sit?
Sitting places direct pressure on the inflamed bursa at the sit bone. This compresses the tissue between the bone and surrounding structures, causing pain.
Hard surfaces increase pressure and symptoms.
Diagnosis
Ischiogluteal bursitis is usually diagnosed based on symptoms and physical examination.
A clinician will assess:
- Localised tenderness directly over the sit bone
- Pain reproduced by pressure or sitting
- Minimal pain with resisted hamstring contraction
Ultrasound or MRI scans may be used to confirm inflammation of the bursa or rule out other conditions.
Differential diagnosis (what else could it be?)
Proximal Hamstring Tendinopathy
Pain is typically worse with exercise and loading, rather than sitting.
Upper hamstring strain
A sudden injury with sharp pain during sprinting or stretching.
Sciatic nerve irritation
Pain may radiate down the leg and include tingling or altered sensation.
Referred pain from the lower back
Pain may originate from the spine and present in the buttock area.
Treatment
Treatment focuses on reducing pressure and irritation of the bursa, rather than loading the tendon.
1. Reduce pressure (most important)
- Avoid prolonged sitting
- Use a cushion or padded surface
- Modify aggravating activities
2. Pain management
- Apply ice or cold therapy
- Gentle movement to prevent stiffness
3. Activity modification
- Reduce running or aggravating activities
- Gradual return as symptoms improve
4. Rehabilitation
- Gentle strengthening once pain allows
- Address contributing factors such as muscle tightness
⚠️ Deep tissue massage may worsen symptoms
5. Medical treatment
- NSAIDs for short-term pain relief
- Corticosteroid injection may be effective in persistent cases
What can a doctor or physio do?
- Confirm diagnosis and rule out other conditions
- Provide tailored advice on load and activity
- Use imaging if required
- Administer injections if appropriate
Recovery time
Recovery typically takes a few weeks to a couple of months, depending on how well pressure is managed.
When to see a doctor
- Pain persists despite rest and modification
- Symptoms worsen
- Difficulty sitting or performing daily activities
FAQ
Why is it painful to sit on my sit bone?
Pressure compresses the inflamed bursa against the bone, causing pain.
Can bursitis and tendinopathy occur together?
Yes, both conditions can occur at the same time, particularly in chronic cases.
Should I massage the area?
Massage may aggravate bursitis and should be avoided if symptoms worsen.
What is the best treatment?
Reducing pressure and avoiding aggravating activities is key.
