Plantar warts are rough skin growths caused by a common virus, and usually develop on the bottom of the foot. Pressure from standing and walking can push the wart inward and make it look different from warts elsewhere on the body. Corns and calluses can sometimes look similar.
When to Request an Evaluation
- A painful or enlarging growth
- Bleeding or changes in the appearance of the area
- Uncertainty about whether the spot is a wart, callus, or another skin condition
- A suspicious skin growth in a person with diabetes or reduced circulation
Common Symptoms
These symptoms can also occur with other foot or ankle problems. An examination can help the doctor identify the cause.
- A rough or grainy spot on the bottom of the foot
- Tiny dark dots within the area
- Pain or tenderness when standing or walking
- A skin pattern that appears interrupted over the spot
How the Doctor Evaluates Your Concern
Foot and ankle symptoms can have more than one cause. The doctor considers your symptoms, health history, and examination findings, then explains what the findings mean and what may come next. She discusses testing, procedures, or additional care only when the evaluation indicates they may be appropriate.
Things That Can Contribute
