Headache pain of ear, nose, throat, and sinus origin.

Pain of the ear, nose, sinuses, and throat is commonly encountered in clinical practice. For the most part, the pathologic process responsible for the patient's symptoms is easily identifiable after the physician performs a targeted history and physical examination. Unfortunately, the nature of this anatomic region makes it possible for the most thorough physician to miss pathologic factors that may ultimately harm the patient. For this reason, the following rules for the treatment of ear, nose, sinus, and throat pain serve both the patient and the clinician well: (1) take a targeted history; (2) perform a careful, targeted physical examination; (3) heed the warning signs of serious disease, such as fever, constitutional symptoms, or weight loss; (4) image early and frequently if the diagnosis remains elusive; (5) perform laboratory tests that help identify "sick from well," such as erythrocyte sedimentation rate, hematology, and blood tests; (6) avoid attributing the patient's pain to idiopathic or psychogenic causes; and (7) always assume that you have missed the diagnosis.
