Male patient, 88 years old. At the time of presentation, herpes zoster was 40 days old and had been treated with antiviral therapy at an outside hospital, and the herpes was nearly healed, but the pain was severe and often kept him awake at night because of the pain. The location of the pain was consistent with the area of herpes, and it was severe cut-like and electric shock-like pain with tactile sensory pain (touching the skin could cause pain). Treatment was with nerve block and medication. The patient’s pain was significantly reduced on the third day of the nerve block and disappeared on the fifth day; the infraorbital nerve block was done only once because of poor local skin conditions. The medication consisted of Lerica, doxepin and naprozine, and the dose was kept at a low level considering the patient’s age. After one course of 10 nerve blocks, the patient was cured. One branch of the trigeminal nerve has more blisters, up to 25%, and relatively few patients have the second branch. Nerve block therapy is a very effective treatment for painful facial herpes zoster and is not complicated to perform and has less impact on the patient. For patients with post-herpetic neuralgia, nerve blocks are also very effective; in my experience, I have achieved good results in cases where various methods such as acupuncture, plum blossom acupuncture and other traditional medical methods have been tried and failed. Although sometimes it does not completely eliminate the patient’s pain, the majority of them can reduce the pain to a low level. Nerve block therapy occupies an important place in the treatment of facial herpetic pain, and early treatment is advisable.
