I had it so bad, I hardly could walk anymore. I used a pelvic belt for a while, but that did not give lasting relief. I finally went to the Mayo Clinic in Rochester, and after lots of testing it was decided that I need spinal surgery. I had this surgery over 10 years ago, and have not had any sciatic nerve pain since.
All this previous run around with pain pills and what ever, did not fix my pain, but caused slight kidney damage. I wish I would have had the surgery earlier, it would have spared me many years of agonizing pain.
It was called spinal decompression surgery, and it sure did wonders!
