What can these sun blotches be?

Question

After spending a good few hours in the summer in the heat sometimes every other year i would get these sun blotches. They are 1cm radius slightly raised red spots that tingle at first, and then appear. They look like they have a little bit of small pimples on them too. I've had cold sores as well before, but i'm not sure if they are the same thing. please help.

Answer 1

my mother gets something similar on her elbows. hate to answer so poorly, but she has gotten a biopsy and everything -- the doctor is totally confused. go to yours and see if they can figure it out.....
