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. Also called the hemostasis stage, this is the point that the injury occurs. Your body responds to the injury by activating an outpouring of blood, lymphatic fluid, and coagulation clotting to stop the loss of blood. This is the beginning of the repair process. It starts immediately after the injury occurs and typically lasts up to six days.
Your body sends white blood cells to combat harmful bacteria at the wound site, swelling at the wound site starts and the skin begins the repair process. Commonly lasting anywhere from one to four weeks, the proliferative stage is also known as the granulation stage or tissue-regrowth stage. This is where you can see the signs of skin repair: scabs protecting the new skin cells that are growing. Also referred to as the maturation phase or remodeling stage, this stage can last from three weeks to four years.
During this stage, the scab falls off as the new tissue gains strength and flexibility and collagen fibers form scars. When your skin has been cut, your first step in wound care is to wash the wound with warm water and a mild soap. Aside from cleaning, this might alleviate some of the itch and irritation.
There are a few steps you can take to reduce the itch, but patience is what you really need. Contact your doctor sooner if you suspect the wound is infected. Over-the-counter versions should suffice, or your physician may prescribe a stronger option.

Recently, you scraped your knee pretty badly. You cleaned it and made sure to bandage it. Is itching something to worry about? When you injure yourself and cut, scrape, or burn your skin, blood begins to clot in order to stop the blood from excessively leaving your body.
Blood clotting happens thanks to cells called platelets. Eventually, when the wound stops bleeding, a scab forms. The scab helps protect the freshly injured skin from contaminants like bacteria and allows the skin to heal. Underneath a scab, your body is working hard to repair damage to the skin and blood vessels. The body also enlists white blood cells to help clean up any foreign matter and bacteria in the wound.
After some time, a scab will fall off to reveal brand-new skin. Deep wounds and severe burns require emergency medical treatment. But most small nicks, cuts, scrapes, and surface burns heal well on their own in a healthy person. Itching occurs as a normal part of healing. However, the reason the itch develops isn't completely understood. One study from suggests that the same mechanisms at work with eczema itchiness are involved in itching during wound healing.
Additionally, itching that occurs during wound healing might be the result of poorly translated nerve signals. Your brain might receive a signal that your skin is regenerating via collagen synthesis, but that information is translated as an itching sensation. And so, what you feel is that itching sensation. While some experts believe histamines, which are released by the body to help with wound healing, may contribute to itching, research suggests that their effect may be minimal.
Signs that a wound may be infected include:. Scratching an itch feels great.
