What is Frey's syndrome?
Frey's Syndrome is a rare neurological disorder that results from injury or surgery near the parotid glands (which manufacture saliva), damaging the facial nerve. The parotid glands are the largest salivary glands and are located on the side of the face below and in front of the ear. This syndrome is characterized by flushing or sweating on one side of the face when certain foods are consumed. The symptoms usually are mild and well tolerated by most individuals. Relief from symptoms may require treatment in some cases.
