What is this?! I just looked down at the back of my hand just above my wrist/arm and theres tiny spots just visible and they're on the other hand but not so many, and they feel prickly and itchy, i havnt used anything what i'd be allergic to and im REALLY frightened. What could this be? They just look like tiny pink/redish bumps they have spread to the bottom of my thumb.
HELP ME PLEASE.
