I'm 55 and have had the same problem for about 10 years. It is DEFINITELY stress related with me. First I start kind of "wringy" my hands, rubbing them, out of stress. Then the bumps
the back of my thumbs. In the beginning I would just rub my thumbs raw, literally. Then the bumps
started. Palms, between the fingers, con
centrated between the thumb, pointer and index fingers. They sometimes spread up on
to the back of my hands. The thumbs blister the most.
