e prepared a brief explanation of common warts for your reference:
 
Common warts are small, hard lumps with a rough surface that many people experience at some point. These typically appear on the hands and feet, though they can occur elsewhere on the body.
 
Warts can vary in how they look and might appear alone, but they are more frequently found in groups.
 
A common wart typically:
 
* Is round or oval
* Feels firm and raised
* Has a rough, uneven surface, sometimes described as cauliflower-like
* Often develops on areas like knuckles, fingers, and knees
* Can range in size from very small (less than 1mm) to larger (over 10mm, or 1cm) in diameter.
