Sit-bone pain is pain at the bony point beneath the buttock, often worse with prolonged sitting, running, or hills. The nearby upper hamstring tendon can be one source. Other causes of buttock pain need different care, so the location alone does not establish a diagnosis.
Where is the sit bone?
The ischial tuberosity is the part of the pelvis that bears weight when you sit. The hamstring tendons attach near it. Pain there may be called proximal hamstring tendinopathy when the tendon is involved. A bursa near the bone can also become irritated, but bursitis and tendinopathy are not interchangeable diagnoses.
What symptoms suggest an upper hamstring problem?
Proximal hamstring tendinopathy often causes deep, localized pain around the sit bone. Sitting, running, sprinting, hills, or activities that load the hamstring may aggravate it. A sudden pop, marked bruising, or significant weakness after an injury raises concern for a more serious tear and deserves prompt evaluation.
How is the cause identified?
A clinician can ask about how the pain started, examine the hip, back, and hamstring, and consider other causes such as referred back pain or a different hip injury. A painful stretch alone cannot confirm the diagnosis. Imaging is not automatically necessary; it may be useful if the history or examination suggests a tear, another diagnosis, or a problem that is not improving.
What can help sit-bone pain?
Management depends on the cause. For a suspected tendon problem, a clinician or physical therapist may recommend temporarily adjusting painful activities and gradually rebuilding hamstring strength and tolerance. Avoid pushing through severe pain or repeatedly stretching an irritated tendon. A seating change may make sitting more comfortable while you recover. A personalized plan can address running load, strength, and return to sport.
If pain is severe, follows a significant injury, interrupts sleep or daily activities, or is not improving with self-management, arrange a medical evaluation. A red, hot, swollen area or fever needs prompt medical advice.
