The investigators propose to investigate the effect of acupuncture on patients experiencing joint pain from aromatase inhibitor therapy. The investigators will serially measure patient's symptoms and track current medications, joint pain, daily activities, fatigue, and quality of life. The investigators will collect peripheral blood at baseline, weeks 4 and 7, one week after the last acupuncture treatment and 4 weeks after the last acupuncture treatment. The investigators will study the samples collected at the five predetermined time-points to test for immune parameters, such as the innate and adaptive immune responses, as well as the proliferative capabilities and pro-inflammatory mediators reflected in innate and adaptive functional immune responses.
