If you still have pain after shingles has scabbed over, you may have post-herpetic neuralgia, which is a result of incomplete repair of nerve cells that have been invaded by the virus. In addition, oral painkillers such as nabumetone capsules, gabapentin capsules, and pregabalin capsules can be used, and the pain relief effect of these three painkillers is gradually increasing. If necessary, carbamazepine, doxepin, etc. can be used in combination, and some severe cases can be treated with nerve block intravenous closure therapy for posterior neuralgia.
