Okay this has only happened to me in the last two weeks out of the 3 years I have been lifting but I was doing leg press with a good amount of weight (bout 650) and on the last rep of me pressing pretty hard I suddenly got an EXTREMELY bad headache that seemed to be focused more on one certain spot on my head the most and it throbbed really bad. Last week when it happened it scared the **** out of me because I could just see myself having an anyeurism right there lol. But it happened again this week and it happened a lot easier (I was doing less weight this week and wasn't pushing nearly as hard as the week before). Anyone ever had this happen? Both times I quit my workout early.
