Anyone ever had a diagnosis of a herniated disc that was causing sciatica that actually turned out to be piriformis syndrome? How did you come to the correct diagnosis and did your pain resolve? I've been dealing with debilitating sciatica for four months and am starting to wonder if I have piriformis syndrome as a result of the disc issue. I am now thinking that if I can just get My piriformis muscle to relax, my pain might go away. It's tight 10 minutes after stretching, wakes me up all night, spasms, etc. I've ead that this muscle can cause the same sciatic pain has a disc issue. Anyone had this experience?
