I had my first microdiscectomy in 2011 at the age of 37. In April of 2015 I have to have emergency back surgery for another herniated disc and could no longer walk. Now I am experiencing pain when I sit and work. I have Spondylolisthesis now and quite a lot of pain. I have popping in my leg and then a rush of pain. My legs have alot of muscle spasms as well. Anyone in a similar situation? I know have to have the epidural shots and then possibly fusion.
