I wanna start off with Im serious right now. I was doing my 1 set of hack squats today and I think I ****ed up something in my head. I was doing 1 set of 20 hack squats and at about 14, I wanted to give up seriously. I kept on getting to 17 and then, slowly did 18 and felt a lil dizzy and seeing stuff, I continued 19 and finally on 20, my head just felt like it EXPLODED and my head was pounding VERY BADLY for a while, a good 2 hrs or so, then I went to bed, its not that bad of a headache now but its still there. I had to call in to work today because it hurt way too much for me. Gym guy said I mighta busted a blood vessel but I dont think so. Again, my head is still ****y feeling right now. Anyone know what coulda happened and if this will get better or what I can do to make it better? If I remember correctly, I think I was holding my breath a bi ton the last reps. Dont know. I quit working out. Quit supplements for right now. Only stuff I took previously was jungle warfare, chaos, and protein powder. Not sure what happened? Any suggestions seriously? Im worried.
