Answers: how can you tell the difference
Calluses and corns are areas of thick, hardened, dead skin. They form to protect the skin and body structure under the skin from pressure, friction, and injury. They may appear grayish or yellowish, be less sensitive to the touch than surrounding skin, and feel bumpy. Calluses on the hands and feet of an active person are normal. Calluses and corns become a problem when they grow large enough to cause pain.
Calluses generally form on the hands or feet, although they may form wherever there is pressure on the skin, such as on the knees or elbows.
Gangrene is a medical term used to describe the death of an area of the body. It develops when the blood supply is cut off to the affected part as a result of various processes, such as infection, vascular (pertaining to blood vessels) disease, or trauma. Gangrene can involve any part of the body; the most common sites include the toes, fingers, feet, and hands.
It's often the result of a serious accident in which an arm or leg is crushed. Less commonly, it follows an internal blockage, such as a clogged or obstructed artery.
