I didn't really know where else to post this so i'm just posting here. Just a little bit ago i was doing flyes and all of a sudden i felt something pop in the front right side of my head, i instantly got a headache and had to stop working out. I'm not sure what it could be or if it has happened to anyone else. I still have a bit of a headache at the moment and am hoping it's nothing serious. Anyone have any idea?
