I'm new here and hoping somebody can help me. Had fusion on L4 Aug. 2007. Before the surgery I always had pain on left side of lower back and down left leg. A few months after surgery, started to have pain in right leg and right side of lower back. The surgery didn't help, it just added to the problems I already had, now I dealing with low back pain on both sides and pain in both legs. Have a hard time sleeping,walking makes both my legs hurt,sitting relieves the leg pain, but if I sit too long my legs go numb. Finally convinced my neurosurgeon of how much pain I was in,so he ordered a myleogram. Now he tells me I have some narrowing above where I had the fusion and this causing my leg pain. Now he tells me I may need more surgery. What does this mean?
