Every household needs this book because symptoms are often early warning signs of underlying illness - we should all be attuned to them. It describes in the simplest and most friendly way ever devised for the ordinary reader what is likely or unlikely to be wrong. For every symptom, there are always several diagnoses. A sore throat could mean a common cold, a dental infection or even an adverse drug reaction. This book sorts the diagnoses into three headings: Probable (common cold), Possible (throat infection) and Rare (adverse drug reaction). As of course there is usually more than one symptom to an illness or disease, you are told what the others are too: invaluable, in fact essential, for completing the diagnosis. This book frees you from unnecessary worry but also tells you when you must seek a doctor's advice. There is a very large market indeed for this book: Individuals, families, the workplace, schools and even entry-level health service workers and professionals.
