At the gym the other day and I was in the middle of a set and I heard this guy start yelling. He was squating on a Smith machine w/ alot of weight (no stoppers in place) and he got pinned down with his head so far between his legs he could have blew himself..Anyway, I ran over and grabed the one side of the bar and jerked it up, and when doing so I "think" I pulled something in my shoulder. It's not really really sore but I got this tingling feeling in it. My question is: Would you know if your shoulder was seriously injured? I know this might sound like a stupid question but I never had this tingling feeling before, and I have pulled muscles in the past so I know what a pull feels like. Have any of you ever had this tingling feeling in a muscle before?
Thank,
M
