When should a specialist be consulted?
The most appropriate person to evaluate allergy problems is an otolaryngologist (ear, nose, and throat specialist). Aside from gathering a detailed history and completing a thorough examination of the ears, nose, throat, head, ENT doctors will offer advice on proper environmental control. They will also evaluate the sinuses to determine if infection or structural abnormality (deviated septum, polyps) is contributing to the symptoms.
In addition, the doctor may advise testing to determine the specific allergen that is causing discomfort. In some cases subcutaneous immunotherapy (allergy shots) may be recommended.
