Having sharp pains in the back of my head when lifting hurts really bad. From what i understand it was from my breathing while lifting heavy. Looks like i have to take a few weeks off. pissed off
It's probably from a spike in blood pressure. Can be caused by caffeine in pre w/o drinks or sides from an anabolic compound if ur running one. Had rear of the skull headaches b4 as well. Were always caused by one or the other.
