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.
"Tired feet" are not a medical condition, but are a common complaint related to various medical conditions. Abnormal foot structure (flatfoot or high arched foot) can overburden the foot, resulting in muscle fatigue. Obesity, improper footwear, pregnancy, leg swelling, increased activity level, or compensation from an injury (through overuse of other parts of the foot and/or the opposite foot) are other potential factors in the development of tired feet.
