While reading the first 3 chapters of this book, I started crying because Dr. Ivker understood and described in detail what I was going through. If you have ever felt like your sinus problems are ruining or controlling your life, and all the doctors can do is give you an antibiotic or a decongestant, then you need to read this book. If you live in an urban or agricultural area, you will be especially interested in what Dr. Ivker writes about air pollution's effects on your condition. The author has suffered with lots of sinus problems himself, in addition to the thousands he has treated, so he knows what he's talking about. The book gives very practical and specific suggestions regarding diet, vitamins and supplements, exercise, and environmental changes you can make in and around your home. This book pulls together in one place everything I've been able to find on the topics of sinusitis and allergies.
