 The primary purpose of this study is to evaluate the efficacy of hypnosis for reducing musculoskeletal pain MSP in women taking aromatase inhibitors AIs for breast cancer. Research indicates that AIs are associated with musculoskeletal pain in up to 61 of breast cancer survivors. AI-associated MSP can include joint pain in the wrists, hands, and knees; carpal tunnel syndrome and trigger finger; and decreased grip strength, morning stiffness, and general muscle pain. MSP can lead to difficulty performing daily activities and can reduce quality of life in breast cancer survivors. This pain is not only aversive in and of itself, but also is associated with non-adherence to prescribed, daily AI regimens. In some studies, AI non-adherence estimates were as high as 50.
