Foot and ankle problems usually fall into the following categories:
- Acquired from improper footwear, physical stress, or small mechanical changes within the foot.
- Arthritic foot problems, which typically involve one or more joint.
- Congenital foot problems, which occur at birth, are generally inherited.
- Infectious foot problems, which are caused by bacterial, viral, or fungal disorders.
- Neoplastic disorders, usually called tumors, which are the result of abnormal growth of tissue and may be benign or malignant.
- Traumatic foot problems, which are associated with foot and ankle injuries.
An uncontrolled urge to move one’s legs is referred to as "restless legs." This can happen while trying to sleep, while traveling, or any time the legs are at rest. There is no known test to diagnose the problem; instead, the foot and ankle surgeon considers the individual’s history to determine possible causes of the symptoms.
