Why do stitces always itch?

Stitches do not always itch. However, when they do, it is usually due to a combination of factors:

- Inflammation: Stitches are essentially small wounds, and like any wound, they can cause inflammation. This inflammation can lead to the release of histamine, a chemical that causes itching.

- Dry skin: The area around stitches can become dry and irritated, which can also lead to itching.

- Allergic reaction: Some people may develop an allergic reaction to the material used for the stitches, which can also cause itching.

- Nerves: Stitches can sometimes irritate the nerves around the wound, which can cause a sensation of itching.
