Summarize:

Because diabetes puts you at high risk for slow healing sores, it's important that you get your callus checked by a doctor. Even with home treatment, your callus can become an open sore that gets infected. This can make it hard to recover. Make sure you call or visit your doctor before trying to treat your callus. Your doctor may recommend medical treatments to help you heal faster, or they might just monitor your progress while you do home treatments. Calluses are typically not serious, but they may lead to an infection if your skin breaks open. Typically, you won't experience any pain from a callus. However, it may start to feel painful or swollen if you develop an infection or you have broken or injured skin. If you notice any pain or inflammation, see your doctor to make sure everything is okay. Your doctor can offer you medical treatments to speed up your recovery. If your callus gets infected, it can quickly become a serious issue. Don't hesitate to see your doctor. You can usually get rid of a callus on your own. However, sometimes they can be stubborn, especially if they're very thick. Fortunately, your doctor can offer you additional treatments that may work for you. Talk to your doctor to find out if this is an option for you. Tell your doctor how long you've had the callus and what you've done to try to remove it. Your doctor may want to do an X-ray to make sure you don't have a foot abnormality that's making the callus get worse. In addition to home treatments, your doctor can do a medical procedure. This may include removing the top layer of the callus or using medication to dissolve the callus.
Talk to your doctor before treating your callus if you have diabetes. Consult your doctor if your callus becomes painful or inflamed. Visit your doctor if your callus doesn't go away with home care. Discuss your treatment options with your doctor if the callus persists.
