In August 2006 I had my third posterior lumbar fusion, L3-L4-L5. Since that time I have lower back pain. I don't think its a problem with the surgery but muscular. It hurts everyday, esp. when I get up in the morning, or do some exercise or try to rake leaves or any work for that matter. I work in the yard for maybe 15-30 minutes and it hurts a lot. Even hurts after 15 minutes if walking. Has anyone been experiencing the same of have any ideas as to treatment? Many thanks.
