Hey guys... Wondering if you guys could give me some opinions. Last week at jiu jitsu i got this this weird feeling in my forearms and my forearms we really weak. It went away a little bit after I was done but still lasted an hour or two. I just finished hockey While I was playing the feeling came back it and it goes from my forearm to my shoulder....uncomfortabl feeling. It hasnt got any better yet and it is worse then when i had it at jiu jitsu. Could it be tendonitis?
