Please help. I had L-5 bone removed L-4 and L-3 cleaned up on 8/13/09. no fusion. staples taken out 12 days later. I have had extreme left leg pain doctor did mri on 9/3/09. said I had a lot of fluid build up, need to have it drained and nerve block injection......... I had 3 nerve block injections 2 years ago. 2 this year the last one didnt relieve back pain but I only had leg pain in my calf. I could of had a third but after 9 months of pain elected surgery. Please note I had one of the top neurosurgeons in the area. I got 3 opinions the first 2 recommended removing all bone from L1 to L5 ( Laminectomy i believe) I figured this would make me needing a fusion down the road.. Any similar experiences with fluid build up after surgery????
