A welt is a raised, often red or swollen mark on the skin, typically caused by an allergic reaction, insect bite, or physical irritation. It has a slightly elevated appearance and may be surrounded by a reddened area. Depending on the cause, welts can vary in size and shape, and they may itch or be painful. In some cases, they can appear as part of a larger skin condition, such as hives.
