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.
Foot bumps are boney projections that can occur anywhere on the foot. They can be a natural enlargement of a foot bone, or they can be an extra bone. They can be asymptomatic (without pain) or symptomatic (painful). If they are not painful, they can usually be accommodated by shoe gear. Painful foot bumps can be treated by the foot and ankle surgeon using a variety of conservative treatments. In some cases, surgery may be necessary.
