Hi, about mid December I started noticing small, itchy bumps around my ankels. The bumps aren't red, so they're not very noticeable to the eye unless you're looking for it. The bumps have progressively climbed my legs and buttocks, where they have a lower profile than on my legs. Recently my arms, the spaces between my fingers, and wrists have starter breaking out. I do my best to keep from scratching, but the itching is getting unbearable, especially at night. What could this be?
