Good evening! My husband who is 29 was diagnosted with Arnold Chiari Malformation in January of this year. We know little about it, except that he has really bad headaches and almost passes out a lot. We want to know some more information, but we just don’t know where to begin. Doctors don’t really know much about it, so they haven’t given us any information. Can someone please help us to understand this and ways to help him?
