I've done that several times. The worst is when u do it and you lose the use of a muscle as a result. For me, I loss my rt peck n triceps. The strength eventually comes back but the atrophy is permanent. I go to a spine specialist. He gives me rehab and stretching exercises. Once it heals, and if I'm good w warming it up n stretching it, I can avoid it happening as long as I play my game that way. Nerves heal about a millimeter a month...so depending on how much of it u pinched, it could be a long time before it fully heals. The doc told me as soon as I get the strength back I can go at it...so I of course didn't listen...nobody else to teach n I can't be in the gym without going live, needless to say, I forced guys to my good side (until the use of my peck n tricep came back) did the rehab and played my game from open guard, didn't let anyone crowd me, and I got thru it. Your best bet is ask a doc...get an mri done to be sure its not too serious n stay away from the guys who jump on your head

we all have disc issues, welcome to the club
