Life would be much simpler for GPs if patients presented with diagnoses. Unfortunately, patients instead present with symptoms that are frequently vague, sometimes multiple and often obscure. Most clinical texts adopt a diagnosis rather than a symptom based approach. Across its four editions, Symptom Sorter has redressed this balance, becoming an essential reference book in primary care. Covering over 100 of the symptoms most commonly found in primary care, this latest, fully updated edition features new entries including failure to thrive and febrile children, anxiety, hip and knee pain, and mouth lumps and marks, all explored through the 'red flags', 'top tips' and 'ready reckoner' format for sorting symptoms that has made previous editions so popular and respected. All general practitioners, especially GP trainers, GP registrars, young principals, nurse practitioners and A&E nurses will find this book an invaluable reference.
