<![CDATA[Cyclical mastalgia, or premenstrual breast pain, is a common complaint among women of reproductive age and is closely associated with the menstrual cycle and emotional conditions. This condition may interfere with daily activities and significantly reduce quality of life. From the perspective of Traditional Chinese Medicine (TCM), cyclical mastalgia is commonly related to Liver Qi stagnation, which is often triggered by emotional stress. This study aimed to describe the implementation of acupuncture care for patients with premenstrual breast pain at Zahira Medica Clinic, Hong Kong. This study employed a qualitative approach using a case study design involving one female participant aged 28 years who had experienced cyclical breast pain for approximately two years. Data were collected through the Four Diagnostic Methods of acupuncture, including observation, listening and smelling, inquiry, and palpation, using a Client Data Form as the primary instrument. Acupuncture care was administered over six treatment sessions in early December 2025, based on the principle of regulating Qi flow and harmonizing Liver function. The acupuncture points used included LR3, LI4, CV17, SP6, ST36, PC6, and GB34, with sedative manipulation techniques. The results demonstrated gradual clinical improvement, characterized by a reduction in breast pain intensity, decreased chest tightness, improved emotional stability, and changes in pulse quality from tense to normal. Based on the evaluation outcomes, the prognosis was classified as good (bonam). In conclusion, acupuncture care based on TCM syndrome differentiation may provide beneficial effects in reducing premenstrual breast pain and can be considered a safe and effective non-pharmacological therapeutic approach]]>
