My right hand has a very different looking, concentrated rash on the back of my
index finger (plus a small single dot on my middle
finger). Both hands developed the rashes on the same day. It never itched or raised up, you can't feel there's anything there. They started out redder than they are now, they seem more brownish now. I've attached a photo of both hands, ignore the dark red scar, that is a burn mark (I burned this finger after the rash had developed).
