I'm allergic to heat and cold (and sweat also causes problems). Used to have allergic to touch, but for some reason it's gone now. My skin can become pretty bad looking at worst, but it's nothing dangerous as I don't have swollen throat or anything, it's just fucking annoying when you get all the itchy red rash and stuff, though gladly it only lasts for about an hour. Funny thing is that the allergic reactions don't happen all the time even if I'm excersising and get all sweaty or if I'm sunbathing and such. So it's kinda random, but the doctors couldn't figure out why, and there was no real medicine for this either. It fucking sucks, and has partly ruined my life :/ Good thing is that every year it seems to get very slightly better, again with no logical explanation.
