Less than a week ago, a red blotch appeared on my left hand- about the size of 1/4 of my palm. At the same time, a small red blotch appeared on the middle knuckle of my right hand. They haven't spread or changed size. The only changes I have seen are small blisters that appeared the first day on my left hand in the bottom portion of the blotch. They appeared when I got the rash wet but have since dried up leaving a dry spot on the larger blotch. No more blisters have appeared. The blotch is mostly the same color- a pinkish red, with the bottom portion that is dry being a little darker. No other symptoms have been noticed. Any ideas as to what this could be? It almost looks like a burn, but since I haven't been burned, I ruled that one out. Any help is appreciated.
