Itchy wound healing

Introduction Wound healing and itching is actually related to the skin structure of the human body and the ability to regenerate tissue. It turns out that the human skin is divided into two layers, the epidermis and the dermis, and the subcutaneous tissue is under the dermis. In addition, the skin also has appendages such as hair, sebaceous glands, sweat glands, and nails. Different skin structures have different feelings about the wound. Because the regenerative capacity of various tissues of the human body is different, the nerve tissue is less regenerative. Generally, when the nerve is fast and long, it is also a good time for the wound to grow fast. When the nerve endings grow into the connective tissue, the wound can feel itchy and painful.

Cause

The healing of deeper wounds is complemented by a new type of tissue called connective tissue. Newborn blood vessels and nerves grow connective tissue. These newborn blood vessels and nerves are particularly dense, and everyone is crowded together. The newborn nerves are easily stimulated. Because the nerves are very sensitive, they will feel itchy. The regenerative capacity of various tissues of the human body is also different. The regeneration ability of nerve tissue is low, and it appears later in wound healing. Generally, when the nerve is fast and long, it is also a good time for the wound to grow fast. At this time, the new nerve endings and blood vessels have grown into the connective tissue, and the local perception is gradually restored, so the wound will be itchy at this time.

The wound begins to heal, and the pain is noticeably relieved when there is a scar, but the feeling of itching is followed, especially when sweating or weather changes. Diagnosis can be based on clinical characteristics.

Differential diagnosis

Wound healing and itching are easily confused with which symptoms:

Feeling often occurs in mental disorders caused by rabies. It is a kind of mental disorder caused by physical infection.

In the early stage, the patient felt headache, uneasiness, low heat, and healed wounds had abnormal feelings such as itching or numbness. After 2 to 3 days, the violent type shows fear of water, fear of the wind, and fear of light. Water, wind, and light can all stimulate the onset of reflex throat. The patient is nervous, fearful, and irritable. The condition gradually worsened, and there were generalized sputum, neck stiffness, increased salivation, high fever, heart failure, and respiratory paralysis. Ineffective treatment can suddenly die. The sputum type mainly manifests as limb paralysis, coma and death.

Wound healing numbness: damage to the nerve at the wound. Generally, crush injury will seriously damage the surrounding tissues and have a certain influence on the peripheral nerves of the skin. The nerve damage needs to be slowly recovered, and the specific degree of recovery varies from person to person.

The wound begins to heal, and the pain is noticeably relieved when there is a scar, but the feeling of itching is followed, especially when sweating or weather changes. Diagnosis can be based on clinical characteristics.
