The acupoints of Shangyintang, Danzhong(RNl7), Jvque(RN14), Liangmen(ST21), Zhongwan(RNl2), Hegu(LI4), Waiguan(SJ5), Zusanli(ST36), Sanyinjiao(SP6), Taichong(LR3) are selected as main acupoints and used per treatment. The other three acupoints will be chosen one each session according to the syndrome differentiation: Taixi (KI3) for liver and kidney deficiency, Fenglong (ST40) for spleen deficiency and phlegm coagulation, and Xuehai (SP10) for qi-stagnation and blood-stasis. Sterile adhesive pads will be placed on the acupoints after skin disinfection. Hwato-brand disposable acupuncture needles (size 0.30×40mm) will be inserted into the acupoints through the adhesive pads. Afterwards, the acupuncture will be lifted, thrusted and twirled gently for 3 times to achieve deqi sensation and manipulated every ten minutes during 30-minute maintenance.

Sterile adhesive pads will be placed on the acupoints after skin disinfection. The needles (with the handle identical to the needles in the acupuncture group and the body at a size 0.30 × 25 mm) will be inserted into adhesive pads without skin penetration. Needles will be lifted, thrusted and twirled gently for 3 times to mimic real acupuncture. No manipulation will be conducted during 30-minute maintenance.

RECRUITINGThe change from baseline in the numerical rating scale (NRS) score on the worst breast pain.
Participants will fill in the Cardiff Breast Pain Chart to assess the intensity of worst and average pain daily in the form of NRS score ranging from 0-10. 0 refers to no pain and 10 refers to the worst pain imaginable. The highest NRS score on the worst breast pain during the cycle is defined as the final score on the worst pain.
Time frame: Through the Cycle 3 (each cycle is 25-35 days)

Participants will fill in the Cardiff Breast Pain Chart to assess the intensity of worst and average pain daily in the form of NRS score ranging from 0-10. 0 refers to no pain and 10 refers to the worst pain imaginable. The average NRS score on the average breast pain during the cycle is defined as the mean of the average pain score during the cycle.
Time frame: Through the Cycle 1, Cycle 2, Cycle 3, Cycle 6 and Cycle 9 (each cycle is 25-35 days)
Proportion of participants with at least 50% reduction of NRS score on the worst breast pain.
Participants will fill in the Cardiff Breast Pain Chart to assess the intensity of worst and average pain daily in the form of NRS score ranging from 0-10. 0 refers to no pain and 10 refers to the worst pain imaginable.

The change from baseline in the number of days with a NRS score of 5 or over on the worst breast pain.
Participants will fill in the Cardiff Breast Pain Chart to assess the intensity of worst and average pain daily in the form of NRS score ranging from 0-10. 0 refers to no pain and 10 refers to the worst pain imaginable.

Time frame: Through the Cycle 1, Cycle 2, Cycle 3, Cycle 6 and Cycle 9 (each cycle is 25-35 days)
The change from baseline in the number of days with breast pain.

The proportion of patients reported "very much improved" or "much improved" per the Patient Global Impression of Change (PGIC).
PGIC is a 7-point scale reflecting patient's self-rating of overall improvement: "very much improved", "much improved", "minimally improved", "no change", "minimally worse", "much worse" or "very much worse".
Time frame: At the end of the Cycle 3, Cycle 6 and Cycle 9 (each cycle is 25-35 days)
The impact of breast pain on sexual life, daily life, mood and sleep rated by NRS scale.
NRS ranges from 0 to 10, with 0 indicating no impact and 10 indicating influence completely, and higher scores represent severer impact.
Time frame: At the end of the Cycle 1, Cycle 2, Cycle 3, Cycle 6 and Cycle 9 (each cycle is 25-35 days)
The change from baseline in the Sort Form 12-item Health Survey (SF-12).
The SF-12 is a general health questionnaire consisting of 12 questions. It investigates the patient's state of health via 8 different dimensions of general health perception, physical health, limited physical role function, physical pain, vitality, mental health, limited emotional role function, and social functioning. The sores of SF-12 range from 0 to 100, with higher scores indicating better physical and mental health functioning.
Time frame: At the end of the Cycle 1, Cycle 2, Cycle 3, Cycle 6 and Cycle 9 (each cycle is 25-35 days)
The change from baseline in the total and sub scores of Hospital Anxiety and Depression Scale (HADS).
HADS consists of 14 items, which are divided into two 7-item subscales to reflect a state of generalized anxiety and the depression. The respondent rates each item on a 4-point scale ranging from 0 (absence) to 3 (extreme presence). The total scores of HADS ranges from 0 to 42, with higher scores indicating severer symptoms.
