Warts: Causes, Symptoms, and Affected Areas

Warts are benign skin growths caused by the human papillomavirus (HPV). They appear when the virus infects the top layer of the skin, usually through small cuts or abrasions. Although warts are generally harmless, they can be contagious and aesthetically concerning for some individuals.

Warts are more likely to develop in individuals with a weakened immune system, children, or those who frequently use communal showers or walk barefoot in public spaces. Direct skin-to-skin contact or contact with contaminated surfaces can also spread the virus.

Symptoms include small, rough, and grainy skin growths that may appear flesh-colored, white, pink, or tan. Some types of warts have black dots (clotted blood vessels) and may cause discomfort, especially on pressure-bearing areas like the feet.

Warts can occur anywhere on the body, but they are most commonly found on:

  • Hands and fingers (common warts)

  • Feet (plantar warts)

  • Face or forehead (flat warts)

  • Genital area (genital warts – require medical evaluation)

  • Under or around nails (periungual warts)

Oral Prescription Medications

Oral treatments are rare but may be used in cases of widespread or resistant warts, sometimes involving immune-modulating medications.

For stubborn or painful warts, dermatologists may use cryotherapy (liquid nitrogen), laser therapy, electrosurgery, or surgical removal. Immunotherapy or chemical cauterization may also be options for recurrent warts.
