What you can do. 1  If a callus is causing you pain or aggravation, you need to scrape away some of those dead cells so the callus wonât put so much pressure on your nerves. Immediately after a warm shower or bath, when your skin is wet and softened, rub a pumice stone on the callus to remove dead cells.
Calluses often appear on the feet, but friction and pressure can also cause calluses on the hands. People who frequently cycle or use hand tools without wearing gloves can develop them. Repeated kneeling or resting elbows on a table can cause calluses on the knees or elbows. Bunions, hammertoe, and other foot problems and deformities increase the risk of corns and calluses. A bunion is an abnormal, bony bump that develops on the joint at the base of the big toe.
