What looks like a callus between my fingers?

Callus or flat wart: It is possible to get a callus on or between your fingers, for example if you do a lot of handwriting and the pen/pencil rubs too much. There are also flat warts which can look sort of like a callus. Have your doctor take a look at the spot, and they can tell you what it is and the best ways to get rid of it.

Depends on the cause: Many things can cause calluses. Some reasons that one may develop a callus include: viral infections (warts), friction, pressure, repedetive trauma, and a limitation of joint motion. Some genetic conditions may also cause people to develop calluses on the hands and the feet. Treatment depends on the cause of the problem. Have it evaluated by a professional and get the appropriate treatment.
