Neuralgia caused by herpes zoster can be combined with its clinical manifestations and go to the departments of dermatology, neurology and pain medicine. 1. Herpes zoster is caused by varicella zoster virus infection. At the early stage of the disease, skin blisters usually appear, and nerve pain can be caused by the virus invading the nerves, which can be first consulted in dermatology, and relieved by antiviral treatment and local treatment. 2. When herpes zoster develops to the middle and late stages, most of the skin symptoms no longer exist except nerve pain, at this time, you can go to the neurology department for consultation, and adopt the method of nutritional nerve treatment. 3. If the patient has intractable postherpetic neuralgia, the pain is difficult to stop, and cannot be relieved by general treatment or neurotrophic therapy, and needs to be relieved by nerve block, etc., in this case, the patient can go to the Department of Pain Medicine for consultation. For neuralgia caused by herpes zoster, you can choose the appropriate department to visit according to your own situation, and under the guidance of the doctor for treatment.
