Since corns and calluses are the result of friction, irritation or pressure against the skin, they can return at any time if the cause has not been fixed. In other words, if poorly-fitted shoes were the cause and you continue to wear these same shoes, the corns and calluses will likely return.
Fortunately, most corns and calluses can be successfully managed at home with a little care and attention. If at any time you are concerned about a growth on your foot, are unsure of what to do or how to treat, and especially if you have diabetes, prone to infections, or have delicate skin, see your doctor. Your doctor is in the best position to examine your feet, ask about or test for other medical conditions you may have, treat your feet and tell you how to take care of them.
