A papule is a small and raised bump on the skin. These bumps can be red, pink or fleshy and usually less than 1 cm in size. Papules can be caused by various factors such as acne, insect bites, allergic reactions and infections. They may also develop as a result of certain medical conditions such as psoriasis or eczema. While papules are generally harmless, they can itch or be painful. Treatment options vary depending on the underlying cause of the papule, but may include topical creams or ointments, oral medications, or other medical treatments. If you notice any unusual bumps on your skin, it is important to consult a medical professional so that you can get a more detailed examination and start the right treatment for you.
