2 days ago some strange spots apeared under both armpits. They look mainly like one big spot filled (like cicle folded under my armpit - contact surface) with smaller round spots (size 1-1.5 cm). First day they were red, second day changed to light brown (I m fair skin, never tanned) - I ve used some anti-fungal cream. o pain, no ich, no new medications, entire body clean. What it may be?
