Not sure where to put this, but I know this forum gets a lot of action, so maybe someone can chime in.
I’ve been working to up my squat, as it is lagging a bit, so I’ve been squatting 3x a week. Usually I’ll ramp up to 3 work sets of 5, then drop back for some back-off sets. I seem to respond well to the extra volume at lower weights, and my squat max has been steadily increasing. All was good.
Then, recently, I started to get some pain in the back of my neck during 15-20 rep breathing squats. It wasn’t joint pain, it was like a serious blood rush in the veins in the back of my neck, and it would give me a pretty good headache for a few seconds after I racked the bar. I squat high-bar/oly style, so I thought maybe it was just weird placement.
Yesterday, I ground out a 15-rep set on a weight I SHOULD have hit 15 with easily, and felt like I was going to black out. Took a long rest, but as this is the only (yes, ONLY) rack in the gym, I didn’t want to sit there holding my head for too long. I stripped the bar to 135 for a final 20-rep set, and walked it out. My head was still pounding a bit from the last grind, but not so bad that I couldn’t do 135 I thought. I banged out 12 reps, took a sec, did 2 more, started to get tunnel vision. Did 2 more, and now sound was slowing down. Did 2 more reps and the pain in my head was just unbearable. Threw the bar back, sat down and couldn’t decide between puking or crying.
I couldn’t even finish the rest of my work out, as even picking up the EZ bar sent this rush of blood to my head that was literally crippling. Had to take out earbuds, and rode home in silence, as any music was deafening. Was getting pretty worried.
Any idea what this is/was? I’ve still got a pretty raging headache this morning, but aspirin seems to take the edge off finally. I love my high-rep sets, and I love pushing very hard, but this is worrying me that I damaged something. Not taking any meds/supps besides fish oil (~9g/day), some creatine with my PWO shake, and some BCAAs and creatine-blend-thing during training. Sometimes will have coffee pre training, but did not have any yesterday.
