Calluses and corns are layers of hard, thickened skin that form due to excessive pressure or friction over a bony prominence. This thickening of the skin is your body's normal response to repeated pressure or friction. The main difference between the two is where they are found. A corn is simply an area of hard, thickened skin that can occur on the top, between, or on the tip of the toes. A callus is similar in nature, but is larger and usually develops on the ball of the foot or on the heel. Unless you also take care of your foot mechanics, your calluses will just come back. The goal is to minimize focal pressure and rubbing which is a motion associated with Morton's Foot Syndrome, an elevated first metatarsal and over pronation (arch drops and ankle rolls inward when standing and walking). If you prevent your feet from over pronating, your calluses will naturally go away because the skin is not stimulated to protect itself and thicken. Wear proper-fitting shoes, check your feet regularly and keep them moving. Fungus thrives in warm, moist areas, so if you get a fungus infection, treat it immediately. You ask a lot of your hands and feet. You cram your feet into shoes and walk around all day. And you may apply great force to your hands as you work with tools in your job or at home. These actions subject your skin to friction and pressure. Your skin often protects itself by building up corns and calluses — thick, hardened layers of skin. Treatment for corns and calluses usually involves avoiding the repetitive actions that causes them to develop. Wearing properly fitting shoes, using protective pads and other self-care measures can help resolve them. The big toe is the other common site for a corn, also called a callus. Hard corns can appear under the ends of foot bones, on the top of the toe, or on the side of the small toe. Soft corns can develop between the toes. Corns are caused by pressure and friction on the skin of your foot from ill-fitting shoes (too loose is as bad as too tight), ill-fitting socks, high-heeled shoes, or toe deformities such as a hammertoe, the AAOS says. Treatment for a corn involves changing the shoe to relieve the pressure. The patient had the procedure done without any sutures, pins, or casts. This was done with the use of an x-ray camera. The patient had this surgery done over five years ago. Numbness in the big toe is not as uncommon as you think. It is actually very common, and although the causes may vary a lot, many people suffer from big toe numbness and tingling. Usually, the symptoms occur on one side, although this is not necessarily true and can affect both toes at the same time. There may or may not be any pain associated with the numbness.
