Overview

Acupuncture is commonly used for the prevention of migraine and tension-type headaches, and has been found to be effective in reducing both the frequency and severity of these conditions. However, studies on acupuncture for menstrually related migraine (MRM) are limited, and current research has not been able to determine whether its efficacy is due to the actual therapeutic effects of acupuncture or psychological benefits. To address this issue, the investigators have designed a clinical trial to evaluate the efficacy of acupuncture for MRM.
