The course of shingles is usually 2-3 weeks, the rash will mostly subside during this time, and the pain will subside within 1 month, but in elderly people with low immunity and concomitant underlying diseases, it will take 3-4 months or even longer to recover, and there are also some patients whose pain will persist, a phenomenon called postherpetic neuralgia. Herpes zoster is a neuroinflammatory disease of the skin caused by the infection of the body with the varicella-zoster virus due to a low immune system. The main symptom is erythema zoster with clusters of blisters along a unilateral limb, accompanied by pins and needles or burning pain. Herpes zoster is a self-limiting disease, so it is important to seek early medical attention and to wait until the pain has completely stopped before discontinuing the medication to avoid sequelae of neuralgia and prevent secondary infections. Because herpes zoster is a neuroinflammatory disease, the recovery time will be longer. Treatment mainly uses antiviral drugs to improve immunity and nourish the nerves. Patients can take oral acyclovir, valacyclovir or famciclovir under the guidance of a doctor, and if necessary, they can choose to inject adenosine monophosphate or acyclovir injection with vitamin B1 treatment. Patients should pay attention to dietary regimen while treatment, eat more light, easy-to-digest food, fresh vegetables and fruits, avoid spicy and stimulating food, fried, barbecued, seafood hair, and drink more water to help shorten the condition.
