In all seriousness, what kind of bumps? Can you be more specific? I have experienced such a problem, but mine were like literally hundreds of small blisters/bubbles on the inside plams and webbings of my fingers that were itchy. Turns out I have some kind of skin reaction to yellow die in Dial soaps.
At first, they started out with just a few in the webbings and between my fingers. I went to 3 doctors, none of which diagnosed me with any solutions to the problem. Although, everytime I went in, I had exema on my hands because the blisters would pop for a week or two and after the oozing was finished, they dried up, skin healed up, and eventually started all over. It just came to me when I analyzed the occurences and made the connections. I have since then stopped using yellow soaps and the blisters never come back.
I put up with this crap for 3 years of my life in high school. Do you realize how embarrasing it was to not shake people's hand for fear of them seeing the problem? It was really gross...the skin would peel off during exema and my palms looked like sponges, literally. Like someone took chunks of skin out. Painful, it was!
