Herpes zoster is caused by the varicella zoster virus infection. Patients with herpes zoster are allowed to blow on air conditioners, and the main thing to avoid with herpes zoster is straining. As herpes zoster is caused by nerve damage due to viral invasion of nerves, accompanied by a rash, care should be taken to avoid exertion to avoid aggravating the damage to the nerves. The rash should avoid contact with water and hot sweat to avoid infection. When combined with bacterial infections, attention must be paid to the use of topical drugs for bacterial treatment, such as fusidic acid cream, etc. Herpes zoster is mainly treated with oral antiviral valacyclovir or famciclovir, along with nerve-nourishing drugs, such as methylcobalamin, vitamin B1, vitamin B6, vitamin E, etc. Oral pain can also be treated with pain medications, and topical iodophor solution and penciclovir gel can be used topically.
