Hi. I'm 24 old man. Every time i sweat (during exercises or anything that makes me sweat) some red spots appear on my forehead. They have irregular shapes and sometimes they itch a little. Those spots are not swollen and i'm not talking about any kind of rush. Just red spots because of sweating. They pass after 20, 30 minutes.
Please, any help would be great. Thanks in advance.
(sorry for my bad english)
