What is throat clearing? Throat clearing is an instinctive attempt to remove an irritant in the throat by consciously or unconsciously vibrating the muscles in your throat, especially your voice box (larynx). Throat clearing is something everyone does once in a while. It becomes a symptom of a medical problem only when it is a response to persistent irritation or discomfort in the throat. Sensations that induce throat clearing may take the form of minor pain, an itchy feeling, or a feeling of something stuck in the throat. This discomfort may be specific to a structure within the throat, such as your tonsils or voice box (larynx), or the back of the tongue. Conditions that can cause throat clearing include a nervous tic, an infectious disease of the throat, a recent injury to the throat, or a noninfectious condition. Throat clearing, in itself, is not life threatening and may resolve on its own. However, if the discomfort that causes you to keep clearing your throat lasts more than a week or two, and if it is accompanied by other symptoms, you should contact a medical professional to identify the cause. Seek prompt medical care if you have a persistent lump at the back of your tongue or in your throat; a raised, scaly, or thickened area on the back of the tongue or in your throat; white patches on your tonsils; a persistent cough; or a persistent fever.
