I had a very painful sciatic problem a year or two after I was diagnosed with Parkinson's, although I really don't think the two had anything to do with each other. I would walk from the parked car into the store and that was as far as I would get and the pain would start in. The only way I could relieve the pain just a bit was to bend over at the waist for a minute. Muscle relaxants and pain medications helped only in the short term. Mine was not a disc problem so I don't think surgery would have been my answer. I had started seeing a different neurologist at this time and he recommended to the orthopaedist a steroid injection in the lumbar spine. I had two of them and have been pain free since. Sharon H
