I had something very similar happen to my daughter's hand. She has clusters of clear white bumps on one of her hands. I took her to the doctors and they said that she was probally had came in contact with something and had an allergic reaction. They have perscribed me steriod cream to put on her hand 2x a day. Since them its been about a week and a half, and there has not been much improvment, if anything it looks more irritated, and now it has spread to the bottom of her hand. I'm starting to worry that it may be something more serious..
