Symptoms, Causes, And Treatment Of A Sore Throat

8. Miscellaneous Rare Causes

In very rare cases, a sore throat may be caused by an abscess or an infected area of tissue in the throat. Epiglottitis is another rare cause of a sore throat. It occurs when a small piece of cartilage that covers the windpipe like a lid swells up and becomes infected, resulting in an impaired airflow. Both conditions can block the airway and create a medical emergency. Seek immediate treatment anytime there is difficulty breathing.
