Though the topics of 'pain' and 'headache' are obviously linked, these two research fields have in recent years developed at their own pace, often with scant attention paid to the other. By forging closer links between these fields, it should be possible to develop a deeper understanding of both the pain mechanisms associated with headache and a deeper understanding of pain itself. This book brings together researchers and clinicians from the forefront of these two disciplines to explore how the basic pain mechanisms relate to migraine and other forms of headache. With cutting edge research from the frontiers of headache and pain research, the book will be essential for clinicians treating headache sufferers, providing answers to many of the commonly asked questions about the mechanisms of their headache. It will also be of interest to those pain researchers dealing with mechanisms related to headache and migraine.
