Just wanted to get you guys opinions. The past few months I have noticed my pecs cramp up easily after a long workout it usually happens that night if I lift my arms in certain ways. Last night I was laying down and moved my arm a little and my pec went apesh**. It convulsed and then locked up like it was trying to sever itself. I looked down and half my pec had dissapared and seemed to have shifted sides, It was like I had a surgery and lost half the muscle.
It was extremelly painfull and in my convulsions trying to fight it I started shakeing and the other one locked up too. This was about 20 seconds after the onset. The pain was extreme and I did not know what to do plus I started getting cold chills and freaking out so I layed down. My pecs did this for about 2 or 3 minutes and then unlocked themselves and went back to normal. I would have thought I had injured one of them but since both did this I am lead to beleive it may be a diet thing.
The only thing I can think of is lack of potassium since I rarely eat bannanas. Has anyone on these forumns ever experienced this? Any insight that can help me avoid this in the future would much appreciated. If it happens again I will take a picture and post it since my friends all wanna see. I am sure it will happen again since I have had recurring problems like this in my hams but this was the first time for my chest.
