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 often obscure. Most clinical texts adopt a diagnosis rather than a symptom based approach. "Symptom Sorter" redressed the balance and quickly became a key book in primary care. This new edition is fully updated and expanded, and still offers the same concise and practical guidance. New topics include - anal itching, anal swelling, crying babies, eyelid problems, facial rashes and leg ulcers. It presents differentials, distinguishing features, possible investigations and key points, with tips and warnings, for over 100 symptoms commonly seen in primary care. All general practitioners, especially GP trainers, GP registrars, young principals, nurse practitioners and A&E nurses will find this book an invaluable ready reference.
