Most of the neuralgia caused by herpes will gradually disappear on its own. This happens mainly because herpes zoster causes some damage to the nerves in the area of herpes, so it produces different degrees of pain, especially post-herpetic neuralgia after the herpes has healed. This pain usually disappears after a long time, but it can also be controlled by appropriate oral medication, such as oral gabapentin capsules, or the Chinese medicine Yuanhu Pain Relief Drops. You can also take nerve-nourishing drugs, such as methylcobalamin capsules, etc.
