The typical symptoms of trigeminal neuralgia are the immediate onset of paroxysmal, knife-like lightning-like sharp pain in the face when a point (trigger point) in the face or mouth is stimulated by eating, washing, brushing teeth, talking, or even walking vibration or wind blowing, with each attack lasting from a few seconds to several minutes and frequent daily. Because of similar symptoms, trigeminal neuralgia can easily be misdiagnosed as toothache, migraine or glossopharyngeal neuralgia. So, how to distinguish these diseases? Characteristics of trigeminal neuralgia: It is a recurrent severe pain with short duration and trigger point. Characteristics of dental pain: It is persistent, with significant onset at night, aggravated by hot and cold stimuli, deep pain sites, and no trigger points. Migraine: manifests as throbbing headache with visual aura, long duration of attack, up to several hours, sometimes very intense, sometimes accompanied by nausea and vomiting, no trigger point. Trigeminal neuralgia and glossopharyngeal neuralgia can coexist, and sometimes the symptoms are similar without being able to determine which disease is which, which requires consultation with an experienced specialist who specializes in treating this disease to avoid misdiagnosis.
