👉 Veinules are small, round structures that appear in various parts of the body. They can be found on the skin, nails, and hair, but they can also occur in other tissues like muscles, tendons, ligaments, and connective tissue. Veinules can be either solid or fluid, with a thin film of fluid between them. They are often considered benign and harmless, but some people may experience discomfort, pain, or even infection if they become inflamed.
