Anyone had anything like this? I've got an odd pimply rash on the back of my hands, it's in a stripe accross the back of my hand from my knuckles up to about 2 inches above, and goes right from my thumb over to my little finger side. It's worse on the right hand, but is also on the left, but the shape of where the spots is identical. Spots are small, pimply, not itchy or blistered. None on the palms of my hands or anywhere else. Came on out of the blue yesterday morning, not particularly itchy and is worse/more obvious when I'm warm.
