Hello. A circular purplish-red spot had appeared in the middle of the back of my left hand. It does not hurt or anything, just a discoloration. It is not bumpy as well. For a pattern, it had been appearing once in every two weeks or so. Since it doesn't hurt, I would usually just let it disappear by itself and it did but, after a couple of weeks, it would appear again and then disappear. The spot would appear at its previous spot and occasionally, it would appear in a different spot. Sometimes, there would be more than one spot.
