As an instructor, the most common physical complaints I get questions about concern the ears. All of us, at one time or another, have experienced trouble clearing our ears during a dive, and many of us had that "full feeling" follow us around for several days after we have finished diving. Is this an indication of ear damage? Are these symptoms serious? Answers to many of these questions can be found in Underwater Ear and Nose Care by Noel Roydhouse. Written in layman's terms with excellent diagrams and photos, the book demystifies the ear and many of the problems we as divers encounter with it. From how it works, to how it breaks, and how to keep it from doing so, Underwater Ear and Nose Care is a must read for every diver who's ever given his buddy the "something's wrong" signal followed by a finger point to the ear.
