 The physician–patient relationship is also complicated by the patient's suffering ("patient" derives from the Latin "patior", "suffer") and limited ability to relieve it on his or her own, potentially resulting in a state of desperation and dependency on the physician.A physician should be aware of these disparities in order to establish a good rapport and optimize communication with the patient.Additionally, having a clear perception of these disparities can go a long way to helping the patient in the future treatment.
