Diagnosis by Questioning the Patient

This method consists of questioning the patient regarding pain, time of onset, history, habits, and so on. Chinese physicians from the past developed ten essential questions for this purpose concerning cold and hot sensations, perspiration, head and body, urination and bowel movements, eating, chest, hearing, thirst, pulse and color, and the spirits. Subsequently, the ninth and tenth questions have been changed. The ninth question now concerns old diseases, and the tenth question concerns the causes of diseases.
