I have cervical spinal stenosis which is the narrowing of the spinal column that causes pressure on the spinal cord, or narrowing of the openings where spinal nerves leave the spinal column. Mine is caused by arthritis. It caused three things--pain in the neck and shoulders when riding long distances on my bike, numb fingers in my left hand, and a weak left arm. I pursued physical therapy to strengthen my upper body to help make up for the fact that I have a bad neck. The exercises have helped a lot and I can't ever back off of them or I have a problem.
I was told that I probably have 5 years of upright bike riding left. And I may have to ride more and more upright as time goes on. This is one reason I jumped on buying my Madone this year, when I was going to wait until spring. I don't want to lose winter riding in Texas this year.
My only advice is that if PT is recommended do it and do the exercises religiously. What a difference it has made for me. I've read that exercise is the best thing for arthritis and keeping it up is vital.
