Migraine is an extraordinarily common, disabling, and painful disorder that affects over 36 million Americans and costs the US economy at least $32 billion per year.

In this book, Joanna Kempner argues that this general dismissal of migraine can be traced back to the gendered social values embedded in the way we talk about, understand, and make policies for people in pain.
