Why do you feel itchy when wounds are about the cure?

The sensation you experience when a wound is about to cure is not strictly the itch; instead, it is called pruritis. Pruritis is a term used to describe an unpleasant sensation that triggers the urge to scratch. Here are a few reasons why wounds may cause pruritis during the healing process:

Fibroblast Activity: As a wound heals, fibroblast cells in the skin start producing new collagen fibers to repair the damaged tissue. This process can lead to the release of histamine, a chemical that stimulates nerve endings and causes itching.

Inflammatory Response: During wound healing, there is an inflammatory response that involves the release of certain chemicals and compounds. Some of these substances, such as cytokines, can activate nerve fibers associated with itching.

Nerve Regeneration: As the wound heals, nerve fibers damaged during the injury start to regenerate. This regrowth process sometimes leads to temporary over-sensitivity, which may translate as itchiness.

Dry Skin: The newly formed skin at the wound site may initially be drier than the surrounding skin. Dryness can further stimulate nerve endings, leading to a feeling of itchiness.

Allergic Reaction: In some cases, the materials used in dressings or skin treatments might cause an allergic reaction, leading to itchiness.

It's important to resist the urge to scratch the wound, as this may cause further damage or prolong the healing process. If the itching becomes unbearable, it's advisable to consult a healthcare professional for appropriate treatment and advice on managing the itch.
