they start out small and grow to almost look pimple like but no head, then stay that way for a week or so then start going away reverting back into my skin and end up looking almost like a dimple before completely disappearing they are redish in color ....this has been going on for about 2 years now. They are not painful if left alone but if i do happen to scratch, or bump it, it hurts abit. This last out break, 2 appeared on the top knuckle on both hands of my index finger and one between my thumb and index finger on both hands. Weird how they come and go and how they appear in same spot on both hands at same time. Any ideas? Im wondering if it is RA?
