Herpes is divided into herpes simplex and herpes zoster. Generally, herpes simplex does not cause neuralgia, while herpes zoster causes neuralgia. Because herpes zoster is caused by varicella-zoster virus infection, and it can invade the nerves, it can cause neuralgia. Treatment can be nutritional nerve therapy, such as oral vitamin B1, B12 or oral methylcobalamin tablets, methylcobalamin capsules, and intramuscular adenosine cobalamin injection. If the pain does not subside, gabapentin capsules can be added orally or Leracal can be added orally. If the pain still does not improve, nerve blocking can be used.
