This study observes how MRI technology can be used to                                           learn more about painful periods, and how naproxen (Aleve)                                   can help people manage their menstrual pain. The study involves                           3 in-person visits: A 2-hour screen visit which will include filling out questionnaires and sensory tests, and 2 separate 4.5-hour MRI visits during your period that include taking either naproxen or a placebo drug. Participants must abstain from taking painkillers 8-12 hours before each MRI visit.
