Yes, it is possible for a bump on the calf to resemble a wart. Warts are usually easily identifiable by their characteristics such as a raised bump, disrupted skin lines, the presence of a black dot (small blood vessel) in the lesion, and they can sometimes be painful. It is recommended to consult a pharmacist who can confirm the suspicion of a wart and provide appropriate treatment. Treatments available at pharmacies are effective and suitable for children over 2 years old. It is important to avoid transmission of warts by not touching them with bare hands, sharing towels, or reusing items that have been in contact with the lesion. Keeping the skin dry and applying a bandage if needed can help prevent further spread of the virus. Most warts will go away on their own, but treatment can help reduce the risk of transmission and speed up healing if they are painful or uncomfortable.
