How can u differentiate between sciatica pain & piriformis synrome? pain above & down left buttock & leg hurts to stand sit lay

Inclusive: Piriformis syndrome causes pain because of sciatic nerve impingement. Both true sciatica - sciatic neuropathy, and piriformis syndrome - can be evaluated by physical exam, as well as by imaging and electrodiagnostic testing. These disorders are uncommon, but must be differentiated from a plexopathy or radiculopathy.

Exam, studies, injec: It can be hard and piriformis syndrome as a diagnosis is likely often missed. Physical exam can help, a nerve conduction with the hip in neutral verses internal rotation can tell, response to injection into piriformis is most diagnostic. Also seeing a patient with severe pain running down the leg with a normal looking MRI of lumbar suggests something else like piriformis syndrome might be issue.
