Effects of the change of weather or allergy?
I just got back from Fort Leonard Wood (it was immensely cold), and got back to my home country (tropical weather) and notice after a day or two, that (only) my forearms had some bumps that weren't there before ...they're usually really smooth (when I do get them is when I'm too long under the sun or sometimes even sweat),can this be some kind of allergy? or is it just the change of weather?
