Spinal Stenosis is as serious as a heart attack. It is the narrowing of the channel the spinal cord travels inside the back bone - either by some impingement or degeneration of the spinal vertebrae, which crushes in on the cord, causing numbness and loss of feeling in the limbs. In the extreme, it can cause paralysis. Treatment for mild stenosis is usually physical therapy, in more difficult cases, fusing vertebrae, metal bracing, disc replacement. In any case, getting walloped by a 300 pound lineman 40 times a game is not recommended. I’d proceed with caution before sinking mega bucks into a LT with any stenosis.
