The treatments for postherpetic neuralgia include medication, physical therapy and so on. 1. Drug treatment: patients with postherpetic neuralgia can take oral pregabalin, gabapentin and other calcium channel modulators as prescribed by the doctor, which can help relieve pain. If the patient’s skin is not broken, you can also use topical lidocaine under the guidance of the doctor, which can play an analgesic effect. 2. Physical therapy: Narrow-spectrum medium-wave ultraviolet light, infrared light and ultrashort wave treatment can help the rash subside and promote the recovery of skin lesions. There are many ways to treat postherpetic neuralgia, and it is recommended that patients go to regular hospitals and cooperate with doctors for standardized treatment. The medication needs to be under the guidance of the doctor, to avoid blindly using medication on their own.
