I had a annular tear in my L5 S1 and had to have a disc replacement, then had a decompression. Now I have to have the disc replacement taken out and I'm getting a posterior lumbar fusion and bilateral L5 S1 nerve root decompression. They said it would take 3 to 6 months to recover. Has anyone else had this done and how long did it take for you to start to feel better? How bad will the pain be? My L4 & L3 are herniated, and I have the disc degenerative disease. Will it effect the other disc and would I have to have another fusion in the future? I need to know what I am in for when I have the surgery done.
