For over 8 years I have had lower back and leg pain, my thighs on the outside upper thigh on both legs have been numb for about 3-4 years, which is strange. About 8-9 months ago I started being awaken from a sleep with severe left pain in this area. My neuro has put me on nuerotin, but the pain has gotten worse, I also think I should say that I had an SI fusion and an l5s1 fusion as well. Could my old friend Si be the problem or is this something totally new, and what do I do next????
