After 5 months since having L4 - S1 fusion/laminectomy I am still having lwr back pain as well as extreme nerve pain in both legs. I have been going to PT since end of Dec. I am slowly getting better, but it is very slow. Some days I will feel like I am much better only to relapse after being active (walking, squatting, cooking, etc) for a few hours. I am hoping it will just take more time. All of my doctors say so.
I think you will feel better after PT and time.
