Part of the What Do I Do Now? Pain Medicine series, this timely volume presents clinical scenarios exploring headache medicine and treatments. Headache Medicine is a complex and constantly developing field, often relying on outdated and time-intensive textbooks. The purpose of this book is to educate readers on the diagnosis and management of commonly encountered headache disorders through brief discussion of relevant and specific cases. The book begins with Headache Medicine clinical pearls and red flags. It progresses through primary and secondary headache disorders, using cases to illustrate presentations and then help to guide an approach to evaluation and management. The book follows the same order as the International Classification of Headache Disorders (ICHD-3). Topics include migraines, cluster headaches, neuropathic eye pain, and trigeminal and occipital neuralgia. This handy guide will be of use to physicians and advanced practitioners (nurse practitioners and physician assistants) interested in the practice of Headache Medicine, emergency room and urgent care physicians, neurologists, internists, psychiatrists, physiotherapists, residents, and medical students undergoing a Neurology or Headache Medicine rotation.
