Have any of you ever heard of this before. I caught it on Medical Mysteries about a month ago.
Essentially it happens only to first time surfers, from holding ourselves up with the back hyper extended while paddling. What happens is there is a blood vessel that goes through there that gets kinked, and deprives the spine of oxygen. This leads to paralysis below the kink!
Sure would ruin first session - flapping around like a wounded seagull on your first (and many subsequent sessions) is bad enough, but topping it off with some paralysis would surely lead you back to a hobby involving much more world of warcraft.
