Last year I had a Discogram that showed that although L5-S1 was herniated and L4-L5 was bulging my pain was coming from L3-L4, which didn't show up on an MRI as herniated or bulging. A neurosurgeon wanted to do a fusion of L5 and L4 because these are the discs that show up on the MRI as problematic. This neurosurgeon does not believe in the Discogram as a test. However, a physiatrist I saw recently thinks I should do another Discogram because the first one said that my pain was coming from L3 L4. All I know is that my back is killing me. I am new to this website. Does anyone have any advice?
