Hi. I had my Rhizotomy on 10/24/08. Four sections on the left and four on the right were done. My main problem is on the left between L 4&5 which were severely pinching my sciatic nerve. The majority of the pain is gone which is a wonderful feeling. I am occassionally feeling a muscle spasm in my left back and at times it feels like the sciatic is swollen. Does this sound like something anyone else has experienced? :?
