Differences and similarities between Frey's syndrome and crocodile tears syndrome

Frey’s syndrome is a rare neurological disorder that occurs after damage to the parotid gland, which is responsible for producing saliva. The condition is characterized by sweating and flushing on one side of the face while eating or drinking .

Crocodile tear syndrome, also known as gustatory lacrimation, is a rare condition that causes tears to form when eating or drinking. It occurs due to damage to the facial nerve, which controls the muscles of the face. When the nerve is damaged, it can cause involuntary tearing while eating or drinking.
