Because the wound will grow back after injury, this stage is called hyperplasia stage. In the original injured part, new meat will grow to fill it This new piece of meat is connective tissue. When you are injured, the broken nerves and blood vessels will grow new meat again, so you will feel itchy.

Generally speaking, if the wound bleeds, it hurts the dermis. There are protein and blood vessels in the dermis, and there are abundant nerve endings, which will be stimulated when you grow meat.

However, because the tissue and function of the skin have not fully recovered at this time, the feeling is very vague, and everyone will describe it as "very itchy". In fact, sometimes it is accompanied by a slight tingling.

In the past, old people would say that if it itches, it means that it has gained weight, which means that the skin wound will grow well soon.

But sometimes our hands are hurt, such as being cut by a knife, so that the wound will heal and we won't feel itchy. Why? This is because our skin is divided into epidermis, dermis and subcutaneous tissue.

Usually I cut a small wound with a knife, only hurting the epidermis. When the epidermis heals, it won't feel itchy because it doesn't involve nerve endings.

I feel itchy during the recovery process, but be careful not to scratch with your hands or rub with clothes, because these will aggravate the infection of the wound and make the wound heal more slowly.

When it itches, you can apply the antipruritic medicine prescribed by the doctor, or do something like watching movies and listening to songs to distract your attention. At the same time, we should also pay attention to diet, eat less spicy food and eat more light food and fruit.
