A few months ago, I got smacked with a serious, instant headache, that near as I can figure was "weightlifter's cephalgia" It forced me to stop immediately, sit in my truck for 15 minutes, and then drive home shakily. I took a week off, went back, and got it again. I took 3 weeks off, went back and I was OK. Now, twice this week, I've felt the headache start to creep, but nowhere near as intense as the first time... It only happens when I'm going heavy on something like leg press or bench press. I've been able to, this time, to step back for a few minutes, and then continue my workout, although with a slight lingering headache. I am being very careful about my breathing now. I've been to the doctor, he just told me to take it easy for a while. Since then, I've changed jobs and don't have health insurance yet, so tests and x-rays and shit like that are gonna be out for a while. Thoughts? Is this something that's going to be a permanent thorn in my side?
