I was recently recommended for a microdiscectomy L5 S1. The first doc told me there was a 90% chance that my leg and back pain would go away. At the worst, the pain was in the lower back, hips and down the left leg. after an SI injection in the hip much of the leg pain was relieved...still have numbness along with pain hip, buttock and tailbone area pain (I got no relief from a lumbar nerve block injection). I saw a different neuro today who said that a microdiscectomy probably would not get rid of the pain anywhere but the leg...may or may not help the numbness. The second neuro said that the only way to relieve the back pain would be a multilevel fusion because of disk degeneration, however he thinks I’m too young (40) to do that kind of surgery. At this time leg pain is not the biggest issue. I cannot sit, drive or walk without a lot of pain. Does anyone have an opinion about either doctor's prognosis? I guess I'm not expecting to be pain free, but just need to be able to function normally (somewhat) again. Thanks in advance for you help and support.
