Any doctor/surgeon that is checking for piriformis syndrome (including diagnosis via nerve imaging) should NOT just check for contracture of the piriformis muscle BUT ALSO contracture of the adductor longus muscle in the same leg at or near the adductor canal, which is frequently also associated w/saphenous nerve neuropathy and saphenous vein compression.

It is ALMOST ALWAYS the case that sciatic nerve compression by the piriformis muscle is associated w/saphenous nerve compression by the adductor longus, because it's the contractured AL coupled w/a weak glute medius that CAUSES piriformis syndrome. There is really no other cause.

Attempting to cure piriformis syndrome non-surgically by ANY MEANS without also treating the AL muscle will therefore be doomed.

If you suspect you have sciatica of non-disc origin that is caused by the piriformis muscle of a leg, you MUST therefore also ask your doctor to look for saphenous nerve neuropathy/damage near the adductor canal of that same leg. Piriformis syndrome and AL syndrome go hand-in-hand.

IMHO, the condition should be called piriformis-longus syndrome.
