Hello, on Monday my wife noticed a weird rash on my back about the size of a baseball. It consists of probably 15 or 20 red blotches, each about the width of a pencil eraser. After stupidly googling it I have decided it’s Purpura... the spots are too big to be petechiae and they don’t blanch. The causes for this range from unknown to some pretty nasty C words. My question is is this dr. Visit worthy, or is it more of a wait a while and react if it doesn’t go away after a week or so, thing? I have yet to get myself to the point where this is consuming my life, but I feel the momentum shifting in that direction. Anyone have experience with this sort of thing?
