I have been getting these blood blisters all ovr my legs and arms they go away after a while but they leave these horrible purple marks. what is it?

A doctor has provided 1 answer

Get seen now: This is the palpable purpura of vasculitis until proven otherwise. You'll need a check for medication allergy, cryoglobulinemia, chronic hepatitis carrier state, and a bunch of other things.
