I had L5S1 done march 2016, then had L3/4 Sept. 2016. Then three months later started to feel like a stabbing pain and feeling some warm sensation in my lower back. My Surgeon decided to fuse L4/5 due to the bulging of the disc. He thought that this might address the feelings I had, I also had nerve pain down right leg to inner part of leg. July 2017 I was to have L4/5 TLIF BMP with hardware done. When he opened me up he saw that the pedicle screws were loose and come out on 2 of them, a rod had come loose and cut into my muscle. So my doc had to redo L5S1 and L3/4 and do l4/5. the recovery is still very painful. My Doctor said he had to remove a lot of my muscle due to scar tissue. I hope this is the last surgery i'll have. Rehab was not fun. but I knew I had to use every bit of it to start recovery. I am now having Bayada nurses and PT coming over my house 2 times a week. I found that you should push yourself with exercise and whtever they give you to do. Just remember to not push too far as it can hurt your recovery. Be strong but don't be too strong.
