If you have a few – or many – warts on your skin, help is at hand. Read on to know what causes warts and how you can get rid of them. You’re sitting at your desk, idly reading through an email when your finger touches the inside of your arm. You feel a growth there – on examining it, you notice that your skin has developed a wart without you noticing. When you examine the rest of your body, you find a few warts in other places too. Now you’re worried and wondering if you’ve developed a serious skin disorder. Relax – most warts are harmless and often painless. But they should not be present on your skin at all. What are warts? Warts are a growth of skin caused by the Human Papilloma Virus (HPV) that lives on human skin. Certain factors like poor skin health and reduced immunity can cause the HPV to grow unchecked. When this happens, there may be formation of a wart on the skin. In some cases, the HPV assumes a virulent form and can cause clusters of warts to appear.
