Spinal stenosis

Spinal stenosis is narrowing of the spinal canal. This can develop as you age from drying out and shrinking of the disk spaces. (80% of the disks are made up of 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.
