A clinical analysis of a patient with a rare form of secondary facial pain (Herzenberg’s disease) is presented. The conducted research and pharmacological tests made it possible to exclude such diseases as trigeminal neuralgia, stylohyoid syndrome, TMJ pain dysfunction, dental plexalgia, myofascial facial pain syndrome. The patient is consulted by a dental surgeon to exclude pathology of the parotid salivary gland and sialolithiasis. The patient was treated with broad-spectrum antibiotics for 8 days. Also, supportive therapy was prescribed: desensitizing, vitamins, as well as an anxiolytic and an antidepressant in minimum therapeutic doses for a course of 14 days (with subsequent correction of the dosage and duration of administration) to correct the emotional state of the patient. We recommend a gentle diet (alkaline warm drink, soft food), and a diet that does not provoke salivation. Locally it was recommended to rinse with antimicrobial drugs, phonophoresis, electrophoresis, magnetotherapy. On the 6^th day of therapy, the therapeutic effect was obtained. By the 14^th day of therapy, the pain syndrome was leveled.
