In this new edition of Headache and Facial Pain in the What Do I Do Now? series, the authors have added cases dealing with issues that were not included in the first edition, eliminated several chapters that were no longer topical or in which recommendations were not current, and updated the rest. The book continues to simulate the curbside consultation in our selection of 37 cases about headache and facial pain. Each case poses an important question to be discussed and each are addressed, much as a consultant would do over the phone or in the hallway, using current evidence and experienced-based information.

We have divided this volume into four sections that cover the typical ground for head/face pain consultation: Section 1, Diagnostic Questions; Section 2, Treatment Questions; Section 3, Questions Related to Special Populations; and Section 4 Prognostic, Social, and Legal Issues.
Diagnostic reasoning is presented along the lines of the International Classification of Headache Disorders, third edition (ICHD-III). Additionally, recommendations for adding or modifying new treatment modalities (pharmacologic and devices) that have been approved since publication of the first edition have been incorporated based on updates from the AHS consensus statement. A list of key clinical points again appears at the end of each case discussion, followed by a list of suggested articles or chapters for those interested in doing further reading on the subject.
