MSK causes of buttock pain
- OA hip
- Lumbar spine referral (buttock pain with or without L Spine pain, +/- referred symptoms)
- Sacro iliac joint pain (tender over SIJ specifically)
- Hamstring tendonopathies (usually specific ischial tuberosity pain, worse on bending forward, can be post traumatic or overuse)
- Piriformis syndrome (buttock pain, burning, +/- tingling in sciatic nerve distribution, caused by increase in activity intensity)
History
Rarely traumatic unless hamstring tear/avulsion suspected
Signs
Hip OA frequently associated with reduced range of hip motion. May not have focal buttock tenderness
SIJ source of pain frequently associated with localised SIJ pain on palpation

Hamstring tendinopathy frequently associated with localised pain on ischium
Localised pain to deep palpation in piriformis region in piriformis syndrome (see photo below)
