Not sure where the last thread went, but would like to know if anyone knows how to prevent this....
Yeah, I get this from time to time. It has usually happened in a medical setting where they need to perform a procedure that was unexpected. They tell me what is going to happen, I can talk and joke about it for about 30 seconnds, and then I can feel the sweat starting to build up on my forehead. Things start going a little fuzzy and about this time someone will say "Do you feel alright? You look really pale.". Unless I lay down for a few minutes immediately, I will pass out for about 30 seconds. After laying down, the feeling goes away and doesn't return.
It sucks because in my mind I know whatever they are going to do is not a big deal, but my body has other ideas. From what I understand the blood vessels constrict as some sort of defense mechanism which lowers the amount of oxygen going to the brain. That's why laying down is key to get more blood to your head. It didn't start happenning until I was in my 30s either, which I think is strange.
