SO today I got owned by a 4' wave. I mean - - owned like it was 12'. In a small slab and riding my backhand. Well, that same wedge whacked me in the neck good. It drove me to the bottom/beach and suddenly I couldn't feel my left arm. I already have some slipped discs in my lower cervical spine but this was a new sensation (or lack there of). I got feeling back in 5 minutes or so but I still can't feel my finger tips on left hand (it's been 4 hours). Anyone out there have expertise in the medical field?
