The overall shape could change due to a bone fracture that would also need the attention of a physician. Stress fractures are very small breaks in the bone that will not usually change the shape of the foot, but may cause pain or bruising. The color of the foot is important as it helps show any changes in blood flow to the foot. Darkening or loss of hair may indicate that the blood supply has decreased. Less blood to the foot can mean slower healing of cuts and scrapes.
Bruises indicate injuries.
Especially important are the bruises or cuts found during a foot check that the person was not aware of at the time of injury. Any bruises within calluses are particularly important to show to a physician. To monitor sensation, a feather or facial tissue can be used to brush the foot and test its ability to feel light touch. Shower water can be first tested with the hand and then with the feet to identify any loss of temperature sensation. By checking their feet daily, they can see any new wounds and monitor healing areas.
