Does anybody else experience headaches when training from time to time? Last night I was finishing my last set of squats (I end w/a 20-rep set), and the second I racked the weight I got hit with what was one of the worst headaches I've ever experienced originating from the top/rear of my head. I let the pain subside and finished my training, which was probably not too smart, but once the pain subsided any pain that came back was bearable.
Today I hit chest, and after I racked the bar after a set of inclines it hit again, this time not as intense. But once it subsided this time it did not come back. Anybody else experience this?
