I was diagnosed two years ago with severe Spondylolisthesis in my lumbar region specifically L3, 4 and 5. After a great deal of trying to manage the pain I had surgery on Oct. 12th and it was quite successful. My MD did a Laminectomy and fused 3,4 and 5.I am now three months out and back to work and doing an aggressive PT program. I have virtually NO Stenosis pain in my back but my left leg still remains very weak and seems to go numb for no apparent reason. I am thinking this is a nerve related issue and will recover over time. Has anyone had a similar problem and how long did the nerves take to regenerate?
