Anyone got any ideas what this could be? I get them on one or two of my fingers very rarely and they disappear after a couple of days, but I'd like to know what it is.
I tried to take a picture, but it's too small to show up properly.
Simply, as described in the title, over a square inch or so of each affected finger.
A doctor once told me it was related to cold sores, but the only information I can find on that is on herpes whitlow, which is basically cold sores on the fingers, and these are nothing like cold sores.
