The symptoms of Frey's syndrome are redness and sweating on the cheek area adjacent to the ear (see focal hyperhidrosis). They can appear when the affected person eats, sees, dreams, thinks about, or talks about certain kinds of food which produce strong salivation.[3] Observing sweating in the region after eating a lemon wedge may be diagnostic.[2]
