So here's a question that I've asked a couple times and no one's been able to answer. Since we have a board where it's related, maybe this means that I'll find an answer.

So before anyone asks, I'm a pretty damned fit person. I eat well, work out fairly often, walk back and forth from work each day, drink lots of water. Despite all this, I find that whenever I walk really fast (or do much moving at all during the summer) my body starts to feel like, well, pic related. Lots of itchy burning crawly feelings, mostly around the area of my torso. This also happens a lot this time of year, when I walk into a warm building after taking a long walk in the cold. Basically, my body reacts to overheating by feeling itchy all over my torso. Can anyone tell me why it might be doing this and what I can do to make the pain end?

What did you doctor say?

I have the same thing although I allways assumed it was just poor circulation because I'm far too unfit, Now I'm concerned...

Some people get hives from being in the cold. My mother, my brother, and I all get hives from the cold, so it's probably genetic.

There are no physical signs of it on me though, just the sensation. And it's not so much the cold as my body being too warm in a cold place or too cold in a warm place and then reacting weirdly.

I always had something like this, any physical activity and I would feel all itchy but then I lost 80 pounds and haven't had it happen since.

It doesn't necessarily have to be visible. My brother gets visible hives, but I don't.
And some people react adversely to rapid temperature fluctuations. For example, for me, if the weather changes pretty quickly, I get very congested and my ears won't pop, as if I'm in an airplane.

This is a normal sensation actually, despite how odd that sounds. It is actually the blood in the ends of your capillaries (very, very small arteries) getting very cold and sluggish and icee-like (can even freeze--frost bite). The sensation you get when walking into warmth is your blood thawing and the ice crystals moving through the capillaries with difficulty and sometimes scratching their walls.
Sounds scary but nothing to worry about as long as you try to keep as warm as possible in the cold and remove layers indoors.

Oh god, the ear thing drives me NUTS. If it's really cold they can hurt like crazy.

errr not sure there...sounds like dehydration actually. I get that ONLY after shoveling snow or when I'm working out and it's warm and usually I'm dehydrated
