WartsWarts

A wart is a small lump on the skin caused by a virus. Although it can sometimes look unpleasant, it is usually harmless.

Symptoms

• Appearance: it looks like an unusual or rough lump on the skin; in the episode, it appears on a paw or hand.
• Sensation: it is usually painless, although it can sometimes itch or feel uncomfortable.

The virus that causes warts can pass from one person to another or spread to other areas of the body:

• Direct contact: by touching another person's wart.
• Indirect contact: by touching objects or surfaces previously used by someone with warts.
• Self-spread: by touching a wart and then another part of your own body.

Many warts go away on their own. When treatment is needed, a healthcare professional may recommend different options:

• Topical treatments: medicated products or plasters applied to the wart according to the instructions provided.
• Liquid nitrogen: a professional freezes the wart with a very cold substance to help remove it.

Aftercare

After liquid nitrogen treatment, follow the healthcare professional's instructions. In general:

• Keep the area clean and avoid scratching it.
• If a blister appears, do not pop it.
• Mild discomfort, a scab or a blister may occur for a few days.
• Once the skin has healed, protect it from the sun.
