About 6 or 7 hours ago I realized that I had these tiny bumps on my hands, my left hand isn't as bad as the right hand though. The bumps on my right hand go a little past my wrist. They are not itchy and the only really noticed them when I left my house to go to a store. Its not contagious because my sister and parents didn't get it. Can anyone help identify it? Here is some background: when I was younger I had eczema but it wasn't that bad and it wasn't like these bumps, I mean these don't even itch. Another thing I feel I should add is that yesterday I spent most of the day outside in direct sunlight for about 6 hours in my school's Senior field day where I was sweating (maybe that has something to do with it?) These bumps are only on my hands and they don't spread when touch over parts of my body, I think it might be my skin starting to peel but I want to make sure. I know its impossible to say exactly what it is over the internet but I tried to add as many details as I could from today and yesterday to help in that decision. Please help me and thanks in advance to those who help!
