Postherpetic neuralgia can be treated by taking measures such as oral nerve-nourishing medications, anti-inflammatory and analgesic medications, and physical therapy. Herpes zoster is a skin damage caused by varicella zoster virus infection. The viral infection will damage the nerves and cause neuralgia, and even after herpes recovers, it may still cause neuralgia and other sequelae. 1. Nutritional nerve drugs: commonly used drugs include vitamin B1 tablets, methylcobalamin tablets, adenosylcobalamin and so on. 2. Anti-inflammatory and analgesic drugs: diclofenac sodium, ibuprofen, gabapentin, pregabalin and so on can be chosen. 3. Physical therapy: you can also choose infrared rays, spectrum therapeutic instrument and other physical therapy measures to promote the recovery of nerve function to relieve the symptoms of neuralgia. It is recommended that patients with postherpetic neuralgia go to the hospital in a timely manner and use medication under the guidance of the doctor.
