Query: Excellent Overview & Guide

As a 20-year migraine sufferer, I must have 50 books on the subject including textbooks used in medical schools and costing $100 or more. This book gives a great overview and introduction to the person who is trying to find out where to start to take charge of their own medical treatment for Migraine and what questions to ask your Doc to see if he really knows what he is talking about. Most don't. This is a "First Step" book and not a book full of answers, but it will help you find more definitive information and save you wasting your time and money on a Doc who hasn't got a clue as to the discoveries about Migraine using Positive Emission Tomography since the late 1990's. Everything "taught" MDs about Migraine prior to about 1995 is just simply UNTRUE and this book will help you find sources for the latest material.
