Symptoms and signs are the first indication of a dysfunction within the systems in the body. Giving these symptoms names may be convenient and help in the communication. Osteopathic medicine recognises the value of a medical diagnosis and has his own ways to define the underlying dysfunctions. This book will help in making a differential diagnosis when a patient presents with symptoms and signs. But keep remembering the quote from AT Still: “To find health should be the object of the doctor. Anyone can find disease”.
