Dear patient, naproxen can help people with headaches. In most cases headaches are luckily harmless. The MRi ist really just to rule out rare other brain conditions as cause. The naproxen is a common pain medication, it won t cure it in that sense but it will most likely help with headaches. As with most medication, only take as much as absolutely needed. Hope this is helping you, if you have any clarificatons you can get back to me, if this was helpful please kindly rate my answer. Best regards
