I'm 18 and a half years old. I've been hitting the gym consistently for seven months now—five days a week, sessions lasting anywhere from an hour to ninety minutes. Regarding supplements, my rotation has included Optimum Nutrition, MuscleTech, Serious Mass, and Creatine monohydrate. Generally speaking, I'm in good health; aside from the occasional minor cold, I haven't dealt with any medical issues. Headaches have never been a factor for me until recently. This started yesterday and happened again today. Specifically, when I'm mid-set and fatigue sets in—right when my breathing becomes heavy—I develop this intense pain at the base of my skull on the right side. It’s sharp enough that I have to stop the exercise immediately. Once I rest for three or four minutes, the pain subsides. This occurred both yesterday and today. What are your thoughts? Any idea what might be causing this?
