Herpes zoster is caused by varicella-zoster virus infection. Treatment is mainly antiviral and is supplemented by pain relief and nerve nutrition because it invades the nerves and causes pain. Clinically, antiviral agents should be used early and in adequate amounts, usually within 72 hours after the onset of the rash. If the patient is immunologically normal, oral valacyclovir may be given. If the patient has renal insufficiency or is older, the drug dose needs to be adjusted. For more severe symptoms, acyclovir is more effective when administered intravenously. If the pain is severe, follow the doctor’s instructions to take mecobalamin tablets and other nerve-nourishing drugs such as gabapentin and pregabalin for pain relief. The lesions of herpes zoster are erythematous patches covered with clusters of small blisters, and stove glycerine lotion with red light is often used clinically to promote the regression of blisters. During the treatment period, it is forbidden to eat spicy and irritating food and seafood, and to prohibit smoking and alcohol. Keep the skin locally clean and avoid scratching with hands to avoid re-infection. Do not use too much or too hot water when bathing, try to use warm water for bathing.
