Nails protect the tips of the toes from abnormal pressure or rubbing. A nail consists of the part you see and a growth plate which is beneath the surface. Both rest on the nail bed. Frequently, otherwise healthy feet develop nail problems. Ingrown toenails are a common aggravation. Improper trimming, tight shoes, or heredity can cause your nails to grow into the surrounding skin, causing pain and inflammation. Aging nails can get thin and brittle, often due to poor circulation, poor nutrition, or diabetes. They may crack, split, or allow the growth of a fungus infection. A thickened nail can be caused by a fungus infection or an injury. The nail may become thick, yellowish, ridged, or brittle. It may be painful to wear shoes. In time, the nail may loosen and fall off. A foot specialist may treat nail problems with one or more of the following: recommending a change in shoe style, trimming or removing the nails, medication, or surgery. For more information, consult your health care provider.
