Hysteric ball is a manifestation of sensory abnormalities that occurs in hysterical patients, who often feel this sense of obstruction or foreign body sensation in the throat, feeling phlegm or discomfort in swallowing. Patients often repeatedly clear their throats or take anti-inflammatory drugs, but often have little effect, so they are very disturbed, more anxious and nervous. Some patients even think that they have laryngeal cancer or esophageal cancer and other serious diseases, and may repeatedly consult the otorhinolaryngology, stomatology, respiratory medicine, but often there is no obvious abnormality. Most of the time, it takes several years before the patient goes to the psychiatry department.
