I am 65 years old and scheduled to have fusion surgery from T10 to S1. I started experiencing pain down my left leg about 4 years ago. The first MRI revealed I have severe lumbar stenosis. In the process I was also diagnosed with progressive spinal deformity (spondylolisthesis / scoliosis). The curvature has progressed to around 35 degrees and it is now quite visible. I cannot walk more than 1/2 a block or stand still for more than 15 minutes without starting to have severe pain all the way from my left hip to the foot. However, I NEVER have back pain!!! I almost always wear tennis shoes and a semisoft brace to reduce the daily onset of pain. I have been reading the forum and other web sites about all the possible complications including chronic pain after surgery. I wonder if it wouldn't be best to postpone the surgery. However I have been told that as I get older chances are that the curve will be greater and more difficult to correct / improve; being older I may then have to have this inevitable surgery when I already have other health issues; and also the curve may result in permanent nerve damage or damage to other organs (ie., lung and kidney). What do I do???? opinions please!
