(Concern) I have a callus on one side of my sole that has been there for some time.

Recently, I have been feeling a callus on the sole of my little toe and I am experiencing slight pain.

I didn't feel a callus, but as I was walking, I felt a little pain, and when I touched it, I felt something like a callus.

It's just calluses are okay, but sometimes there's pain, so I looked into whether it's a corn, and it doesn't seem to be a wart for sure.

Calluses or corns, but calluses don't cause pain. If the pain persists for a long time, I would go to the hospital.

Unless it's stimulating while walking, I don't really feel much pain. Wearing sneakers and paying attention to it almost eliminates the pain.

If it's a corn, should I go to the hospital for treatment? How much will it cost and how long will it take?
