Clinical symptoms of herpes zoster include red rash, burning pain, tingling or extreme sensitivity in the affected area, usually limited to one side of the body. There might be a fever or a headache. The pain of acute herpes zoster may be severe, but it is usually temporary. Some of old patients are likely to develop postherpetic neuralgia. We treated a 73 year-old male patient who had severe pain and a headache after acute herpes zoster. In the point of Differentiation of Syndromes(辯證), this subject was diasgnosed as wind-heat syndrome(風熱證) and was administered Bangpungtongsung-san. For the purpose of making the pain easier, we used the western medication as well. After six days of treatment, pain and the other symptoms improved. Besides postherpetic neuralgia dissipated. Based on this experience, both oriental medicine and western medicine have a good effect on acute herpes zoster.
