When I ended up having a 5 lvl Lumbar Laminectomy it was because I had been having pretty severe right leg pain. I never did have significant low back pain. I did have pain that originated in my lower back. But the bulk of it was in my right leg.
One month post-op my leg pain has no subsided. My surgeon told me it would take 3 to 4 months before we would know how much of my leg pain would go away.
I had a 4 level cervical laminectomy a yr and a half ago. This was to take pressure off my nerve roots and alleviate pain in my arms. It never did alleviate pain in my arms.
Latest MRI's say I have nerves still being pinched in my neck. My next surgery will be a two level discectomy/fusion with titanium plate and screws in my neck.
For me as long as these surgeries prevent further damage I'm good with it. I'm on Social Security Disability and 58 yrs old. So I didn't have many yrs of work left anyway.
