[Case of red ear syndrome].

This paper reports a case of red ear syndrome, a rare clinical condition, treated with acupuncture. At the initial consultation, the diagnosis was unclear from a western medical perspective. The advantage of traditional Chinese medicine in "prioritizing symptoms and syndrome differentiation" was fully utilized. Based on the patient's clinical manifestations, disease progression, tongue and pulse conditions, the treatment addressed the branch by targeting meridian <i>qi</i> stagnation based on the hand-<i>taiyang</i> sinew meridian theory, and treated the root by selecting acupoints according to syndrome differentiation for liver and kidney <i>yin</i> deficiency. A combined treatment of tendon needling and acupuncture produced immediate results after the first session. Subsequent sessions were administered every other day for a total of ten treatments. The patient's ear pain and redness symptoms had nearly disappeared, and a two-month follow-up showed good overall condition.
