how do you know you have an allergic reaction to the heat and/or sun?
my mother speculates that I may have an allergic reaction to the sun. I haven't done anything differently and have never known to be allergic to anything. my scalp just started burning out of nowhere and it itches like crazy. my right arm has been burning the same and itches. I have little red bumps on my skin. the same ones my toddler gets when its too hot.
