Hi, what can be done for a callus on bottom of foot is causing pain?

Hello, Anon!

Thank you for writing today!

If you have diabetes or another condition that causes poor blood flow, consult your doctor before treating the corn and callus on your own.

If you have no underlying health problems that you are aware of,
these suggestions may help to clear up the callus:

Use over-the-counter pads. Apply a pad to protect the area where a corn or callus developed. Be careful using over-the-counter (nonprescription) liquid corn removers or medicated corn pads. These contain salicylic acid, which can irritate healthy skin and lead to infection.
Soaking your feet in warm, soapy water softens corns and calluses. This can make it easier to remove the thickened skin.
Thin thickened skin. During or after bathing, rub the callus with a pumice stone, nail file, emery board or washcloth to help remove a layer of toughened skin. Don't use a sharp object to trim the skin.
Moisturize your skin. Apply moisturizer to your hands and feet to help keep the skin soft.
Wear comfortable shoes and socks. Stick to well-fitting, cushioned shoes, and socks until your corn or callus disappears.

Sometimes, a callous or corn must be treated by a doctor if they persist despite self-care.
