Frey’s Syndrome

It is a neurological disorder resulting from damage to or near the parotid glands responsible for making saliva, and from damage to the facial nerve often from surgery .

The symptoms of Frey’s syndrome are redness and sweating on the cheek area adjacent to the ear. These symptoms generally appear when the affected person eats, sees, dreams, thinks about or talks about certain kinds of food which produce strong salivation. Observing sweating in the region after eating a lemon wedge may be diagnostic.
