I have callous like tiny bumps on the inside of my hands. Most of which is on the insides of my hands on the fingers. When they start they are red bumps about the size of a pen tip and are tender. When they begin to "dry up" they feel callous like and have pink/redish like dots in the center of the "callous". Although they not are raised a lot you can feel them when you run your fingers across them. There is nothing inside of them and seem to be deeper in my skin. They do not itch at all. Please help
