Any of and all the listed birth issues can pile up for mysterious to deadly results, ie: sudden infant death, which is always thought to be face down suffocation but its more the neck pinching off breathing reflex, so both can add up to no life. In older folks it called sleep apnea, which did in my younger brother Dale, so now have that pain every time the weather is nice and doing stuff we liked together no more. I see failed hip and knee replacements, sometimes twice in same joint respond back to good function pain free by attending to CNS supply more than the local tissues, but hips/legs/feet hold up butt which holds up back which holds up neck/shoulders so must deal with what body shows as priory to support neck recovery. One of the most amazing simple impossible things I've come to depend on now in local tissue injury, surgery to vemoms to burns and slices is plain Jane rubberized magnets over area which Bayler found makes the capillary beds breath instead of just swelling up or choking off. Can take 12-24 hour to kick in but effect lasts 12-24 hr after removal, then found can flair up to useless state, till replaced for a day then dramatically better in every way.
Example of business card magnets magic, had SuVee drop me at 3 mph when tires slipped on wet grass lump rolling to stop w/o brake so momentum twisted R foot completely outward, with firecracker pops of ligaments and tendons tearing off bone attachments then whole weight of bike pointed foot completely straight for sound of breaking rock/glass as ankle bones crushed to a wedge shape. Could only put on a sock so swollen that day, by 3rd day swelling down and could bend ankle enough to put in tie up boot support and not too bad to gimp around. By 4th day could walk with caution no limp bare foot. So good by 5th day, even with all the blood puddle leaked out shattered bone marrow I showed and left magnets off and didn't suffer working all day and sleep all night but awoke on 6th day in shock as R foot was a balloon with blunk nubbings of toe showing like a rubber glove over inflated, no boot that day. Put magnets back on and by 7th day was back to barefoot if I was careful, so kept magnets on 8 more days then neck and minerals kicked in and that was the end of any bother to me. Crunching noises stopped in a few more weeks so ready to tear up another major joint and ignore it after a short while. If bad tissue tares and aligment then surgery helps to get best recovery but not if the nerve/blood supply interfered with, then all kinds of bad side effects and non healing can happen w/o obvious reason.
The main source of say carpal tunnel, tennis elbow and biker position pain is the neck cord and nerve roots, so putting a magnetic on arm will have little effect as not source of pain, so of course it seems like magnets are BS to most. Even so may help locally as nerves make joints wear out and muscle imbalanced soo can help with that minor part of the pain. Magnets on neck help some with the outer soreness but not much for the way deeper mean stuff. Try it and see like I did in desperation a couple decades ago to be rather surprised pleased. Neck can snipe at low back too btw then its shows bad decay but bad decay is seen a lot in cases w/o any symptoms from it, so another medical mystery hehehe.
