What you say CH is mostly correct. There are two primary types of stenosis, Cervical and Lumbar both of which are frequently the result of a form of osteoarthritis. The neck injury in his case didn't cause the problem but, instead, agrivated the problem. He was likely born with the problem. The same symptoms are often caused by problems such as yours, frequently, the result of becoming an old fart like me. Honest CH, I'm not saying you are an old fart. But the narrowing of that nerve passage is often caused by the aging and drying out, so to speak, of the disk because they lose the fluid that makes them flexible which in turn causes the vertebrae to squeeze together. Therapy will often relieve the problem as will several other treatment methods but those are usually short term fixes. You have experienced the numbness and weakness that comes with that type of condition so you can imagine how difficult it would be to perform as a wide receiver in the NFL with numb or weak fingers or hands. I believe they can get him in shape to get on the field again but it wouldn't take many hits to reaggravate the condition and put him right back on the sidelines and that's probably why the doctors only give him a 50-50 chance of playing again. They are concerned about his long term health.
Right. What I had was the crushed disc. Not from being an old fart (at that time anyway) because I was in my early 30's. Mine was from abuse. Foolish lifting... Mine was also crushed to the point of being shut down so I had no choice but to have surgery or have no use of my tricep. Anyway, what I had doesn't matter. But stenosis as I understand it, does not have to do with a disc being crushed, it is when the canal through the bone closes in around the nerve and starts to shut it down. Sort of like carpal tunnel which I also have. One hand fixed, the other not. Bone is growing in and pushing on the nerve.
I'm not sure what Q's neck injury was/is but I'm thinking that is the problem doctors are worried about. Not the stenosis. For stenosis they pretty much route out the channel and you're back to normal. My buddy has it in his neck. He had surgery and pretty much no restrictions afterward. I had 2 screws, a metal plate and a cadaver bone put in and had to wear a neck brace for 6 weeks. My bone was supposed to grow and attach to the cadaver bone. Last time I had it xrayed, I wasn't getting much growth. I was supposed to go back once more but I never did. Wasn't going to change anything. I wasn't about to redo surgery and the doc said it was probably good enough
