Itchy scabs are a normal occurrence. Scabs are formed when a mixture of plasma, blood and exfoliated tissue from a skin injury dries and coagulates, providing some protection to the wound. The skin at the scab is in the process of healing, at this time there will be more local inflammatory cells, fresh granulation tissue and connective tissue, there will also be new blood vessels and nerve tissue, in the process of their own repair to stimulate the surrounding receptors will appear itching symptoms. This itching is not particularly intense and can be ignored. As time passes and the wound surface gradually recovers, the itching symptoms will gradually be relieved. Patients are strictly prohibited from scratching with their hands during and after the scabbing process to avoid bleeding or infection, which may affect the healing of the wound. If the itching is unbearable, you can wipe it with a sterile cotton ball to relieve the itching. However, if there is obvious pain, redness, swelling and pus flow during the healing process, it indicates that infection may have occurred and requires prompt medical treatment. If the itchy area appears obvious red papules, it may be an allergic reaction to the traumatic area triggering dermatitis-like changes, and it is recommended to follow medical advice for treatment.
