I have been diagnosed with a severe allergy problem. After purchasing several books from Amazon and having purused several more at the book store, I can honestly say that this one book is the best written, most complete and scientifically accurate book I have seen for lay people on the subject. It covers everything from how to modify your home environment, to what drugs are available, to what are desensatization shots and what are the results if you take them. It has enabled me to discuss things more intelligently with my doctor. Also I want to warn you there is lot of pseudo-science out there. This book sets things straight about what is the science in allergy diagnosis and treatment and what is just plain nonsense. Read this book before you read anything else. It is quite concise and I found you can jump around and the read the chapters of your choice without being lost.
