Move Against Migraine moderators and AMF partners spoke to Health about what a migraine attack feels like.

Studies show that migraine is more prevalent in women than in men. About one in four women will have a migraine attack in their lives, and in extreme cases, as many as 15 times a month. Migraine attacks don’t just cause debilitating pain, but can also impact relationships, derail careers and more.

Health asked five women with chronic migraine to share their stories and shine a light on this invisible disease. Rachel, Michelle, Eileen, Carly and Katie work closely with the American Migraine Foundation as support group moderators, official partners or both. Read their stories here.
