As the number of medical organizations offering pain examinations increase, the need for well-selected collection of questions with detailed but concise explanations became apparent. Consequently, we have tried to make this book a reasonably complete source of "board-type information" and a "one-stop shop" to practice questions for all the major examinations with included answers and suggested reading so that the reader does not need to use other sources for explanation of the answers.
It is our hope that this book will serve as a source of knowledge refreshment so that readers can get a feel for which pain medicine topics they know well, and which they may need to become more familiar with. We would also like to emphasize our message what this book is about, namely, it helps our readers not only to practice answering questions in efforts to pass their Pain Medicine boards, but most importantly, to truly learn and understand the various pain topics as presented here. Medicine is an ever changing science, for the most up-to-date information readers are advised to consult current literature. Any suggestions for future editions are always welcome.
