The rash is caused by the varicella-zoster virus and is most common in people with low immunity. The rash is usually distributed along a peripheral nerve, arranged in a band, and occurs on one side of the body, not exceeding the median line, sometimes on the opposite side of the median line, and may have a few rashes, preferably on the intercostal nerve, cervical nerve, trigeminal nerve and lumbosacral nerve, usually invading only the unilateral sensory ganglion, with enlarged local lymph nodes. The treatment is mainly anti-viral treatment, while nerve nutrition and immunity regulation can be given. The degree of pain varies in severity and is not necessarily related to the severity of the rash. The elderly can also be left with post-herpetic neuralgia after getting shingles, and acupuncture and local treatment will be more effective.
