I have these tiny pimply bumps mainly around the sides or top of my fingers.. there is no puss.. no heads on them.. just a tiny raised bumps.. in clusters usually.. although they usually start as 1 and grow into clusters.. they are itchy.. although not enough for me to want to scratch them.. they last up to 2 weeks? And dry out.. which then my skin will peel in the area they have been in.. I just started having them last year.. durin the summer.. but during this whole winter.. no symptoms or bumps.. now it's starting to get warmer.. and they have reappeared.. any clues?
