I have a small bump on the inside of my pinky finger. I thought it was a small burn or bug bite, but it has a hard center and a small ring around the center. It is extremely itchy.

My daughter as gotten these same things her whole life and nobody has ever been able to tell us what they are or how to get rid of them. My daughter tells me that they go away on their own within a few days time

One of the people here told me that his mother called them sugar pimples, but nothing comes up in a search under this name. He gets them as well.

What are they, how do you get rid of and how not to get them back?

There are no doctors on this site, and no one can, or will (if they're a doctor) diagnose online. It's too risky.

If you want guesses we can give you tons of guesses, but not a definite answer. Only a doctor can give you an answer to this, and it seems, from your post, that no doctor has been able to tell you what's going on.

You really won't find answers online.
