Life would be much simpler for GPs if patients presented with diagnoses. Unfortunately, they do not - they present with symptoms which are frequently vague, sometimes multiple and occasionally obscure. This text offers a comprehensive. alphabetical guide to the common symptoms encountered in primary care. This updated second edition includes nine new symptoms including infertility, double vision and epigastric pain. Emphasis is placed on easy-to-read practical information with a standard layout for each symptom. Each symptom comprises: an overview; differential diagnosis; ready reckoner; investigations; top tips; and red flags (cautions and warnings) for over 100 symptoms commonly seen in primary care. This text should be of interest to general practitioners, especially GP trainers, GP registrars, young principals and nurse practitioners.
