I am 5 weeks post op from L5-S1 disk fusion. My surgeon informed me following surgery there was alot of nerve involvment that was not seen on any of my MRIs.Following surgery i had no feeling from my knee down on my right leg the has improved now i just have sever pain and burning in my foot and toes. The doctor was treating that pain with Neurontin 3 x day. It made it worse. It is my understanding that the pain is from the nerve trying to heal or die. My question is how long will this last and will it ever get better?
