As with many other parts of the body, problems in the foot and the associated foot pain are usually caused by foot injury, wear and tear, bone disease or congenital flaws. Foot pain is very common. About 75% of people in the United States have foot pain at some time in their lives. Environmental factors, such as poorly fitting shoes, high-heeled shoes or running and walking on uneven ground can all cause foot pain and damage the foot or lead to a foot injury.
