What about herpes zoster itching?

Herpes zoster is a viral skin disease caused by varicella-zoster virus infection. It is characterized by dense small blisters distributed unilaterally along nerve segments, accompanied by obvious neuropathic pain. Herpes zoster is a common skin disease. Clinically, herpes zoster is not characterized by itching, but by severe neuropathic pain. Patients with herpes zoster will show a certain degree of itching during the scab and slow healing process, but this degree of itching does not need to be treated, because this is often a normal reaction in the healing process of the wound. It is generally not recommended to treat this itching alone, because after the patient's wound heals, the itching can disappear on its own. Avoid scratching if itching is present, and take antihistamines if itching is too severe to tolerate sleep disturbances.
