You are correct. Piriformis syndrome rarely manifests as yours, mainly it causes pain in the posterior aspect of the thigh, worse when getting up in the morning and some sensitive points in your buttock. However, if NCS reveals problem with the sciatic nerve, piriformis syndrome can't be rule out entirely or you have a nerve entrapment syndrome elsewhere on the sciatic nerve tract.
