Just curious, but a guy at the local gym keeps having fits. These are becoming progressively more regular. He's a big guy and has used steroids for a number of years (10-15). They are accompanied by a mild pain in stomach apparently. Have witnessed a couple of these, seen him laid on the floor and well 'having muscle spasms' i suppose. These tend to last anywhere up to five mins before they pass. Wondering if any of you guys have any idea if these could be linked to usage of steroids. Havent heard of any side effects like this before myself. Sounds like related to nervous system to me, but thats just a vague guess, as im obviously no doctor.Hes obviously going to get checked out, but im interested in any feedback all the same.
