Herpes zoster does not usually recur after recovery, except in cases where the body’s immunity is extremely low, such as with tumors, AIDS or organ transplants, which often cause a recurrence of herpes zoster. In the treatment, you can choose to take drugs such as acyclovir or ganciclovir, or thin glucagon or sodium deoxynucleotide to improve the immunity of the body. You can also take oral mecobalamin capsules to nourish the nerves and oral gabapentin tablets, Leroca or Advil to relieve pain. Patients need to get good rest and sleep, not to overexert themselves and not to get angry too much, so as to avoid the occurrence and recurrence of herpes zoster due to the decline of immunity.
