i have tiny red bumps over the backs of both of my hands. They are filled with clear liquid and when i scratch (i know i shouldn't), they burst. Some of the bumps turn into huge red raised patces. I also get them on the sides of my fingers. They do not look infected and are not at all dry, they are just smooth bumps.
I have had them for 3 or 4 years running, they disappear most of the tear but i often get a few bumps on my knuckles on a warm day. When it get really hot, like it is now where I am, both the back of my hands get covered in these bumps which spread on the forefinger and around the thumb.
