Why do small open wounds and burns get itchy while healing?
In: Biology
Big wounds healing does the same, we just aren’t as bothered by it because it seems proportional to the injury. Small wounds, well, we’re all very annoyed when they itch or hurt because of just how superficial we can see them to be.
It’s a histamine response, last I read. It gets your nerves all hot and bothered and promotes healing as the skin comes back together.
Mast cells and other healing cells rushing to the site release histamine and therefore an itchy feeling around the wound. Part of the healing process

Scabs also itch for a [reason](https://www.healthline.com/health/why-do-scabs-itch#causes)
New skin growth can also cause itchiness. As collagen cells expand and new skin begins to grow on the wound, it results in a scab. When a scab is dry and crusty, it stimulates an itchy sensation.
These messages of itchiness from your brain are ones that you should ignore. Scratching a wounded area or picking at a scab can tear new skin cells that your body is producing to heal the wound. Scratching the itch can reinjure the wound and set back the healing process.
Mainly histamine release (the same reaction that goes haywire and causes hives during an allergic reaction). The main purpose is to increase blood supply to the area, which is important for healing. Itching is a side effect.
There is also a slight inflammatory reaction from the white blood cells that are hanging out in the area to make sure you don’t get an infection, and the inflammation can cause itching.
