"Sinus pain" describes pain that is in the upper teeth, between the eyes, the ear, or on your face. Other nasal symptoms usually accompany sinus pain and include nasal airway obstrucion, abnormal drainage, or nasal congestion. If the pain is best described as a headache, then start with headache instead. If the "pain" is just a mild pressure feeling, then look at the congestion section instead.
