OverviewSpinal stenosis is narrowing of the spinal canal. This can develop as you age from drying out and shrinking of the disk spaces. (The disks are 80% water.) If this happens, even a minor injury can cause inflammation of the disk and put pressure on the nerve. You can feel pain anywhere along your back or leg(s) that this nerve supplies.
