So I was doing my leg workout this morning and when I got to my second set of hacksquats on the sled I suddenly got this incredible pain where your neck meets the back of your head, it traveled up the back of me head and eventually (by the next 2 reps) affected the whole back half of my head. It was so bad I had to lay on the gym floor for about 5 minutes to get it to dissipate. It started to come back alittle as I wrapped up my workout (towards the ends of my sets) and left me with a small headache I still have.

Has this happened to anyone else?? Does anyone know what causes it or how to prevent it?

Thought I was having an aneurysm or something lol. But if this keeps happening I'll have to see a dr. or something cause its enough to make you stop your workout and think something is seriously wrong.

Thanks for any info or ideas guys.
