Shingles itch is usually a symptom of herpes zoster neuralgia. Acute pain usually gets better in about 1 month, but the time to get better varies due to individual differences. Herpes zoster neuralgia is mainly caused by the varicella-zoster virus invading the nerves, and the patient will have localized itchy skin, pain and other symptoms. After standardized treatment, acute herpes zoster neuralgia can usually get well in about 1 month. However, due to the differences in each person’s condition, physical fitness and immunity, some people can only get well in about 4 months. For patients who develop shingles neuralgia with pain that lasts more than 4 months, which is generally known as postherpetic neuralgia, it is recommended to visit a regular hospital. Relieve the pain under the guidance of a doctor.
