What is a primary symptom of Frey's syndrome?

Frey's syndrome, also known as gustatory sweating, is characterized primarily by excessive sweating in the cheek area during eating, particularly when consuming sour or spicy foods. This condition occurs due to aberrant regeneration of the parotid gland's sympathetic nerves, which leads to sweat production occurring in response to gustatory stimuli. As a result, patients may experience not only sweating but also discomfort or pain in the cheek as their body responds to the sensory signals associated with eating.

Understanding the primary symptom of Frey's syndrome helps differentiate it from other conditions that may cause discomfort or symptoms in the facial region, such as jaw pain or gum swelling, which are typically unrelated to this syndrome. Additionally, numbness in the facial region is more indicative of nerve damage or compression rather than the specific symptomatology associated with Frey's syndrome. By recognizing the hallmark symptom of excessive sweating and pain in the cheek during meals, clinicians can better diagnose and manage this unique condition.
