were you lifting heavy during the day or right before it happened?
when i was going to the canisius college gym a few years back… a few of us decided to push our limits on the leg press machine. badazz was rockin out sets of over 600, i was hittin close to 525… (normally i would do about ~300) then after i finished the set and almost fell off the machine, we moved onto shoulders… i tried one set of shoulder press, but got this shooting pain thru my head. i immediately stopped, and went and laid down in the locker room… but i was woozy, felt like i was gonna pass out, a ton of nausea, and the pain was horrible. anytime i tried to go to the gym and lift ANY weight for the next 3-4 months i couldn’t do it - the pain would come right back.
after awhile, i started going back, but starting over really light… now i’ve worked back up and not had any pains or the other issues… never went to the doctor to see what it was (mistake)… but that shit is definitely scary… let us know if you find out anything about what it was or could have been.
