Hi, I started having some kind of itchy red callusy type bumps on my upper knuckles on a couple of fingers. At first it was kind of random & they would come and go....now the one on my pointer finger has been irritated for a solid week or two....it has split open & is shedding skin & is kind of painful. There are a few random small bumbs that go down the same finger onto the knuckle. I am starting to develop what looks like the same thing on a couple of my other knuckles (upper)....just seems so strange that it is only really happening on my upper knuckles....starts out a little dry and swollen then gets red & itchy, but severity comes & goes....?????
