patients do not report pain during an episode. this is not glossopharyngeal neuralgia although the condition can co-exist with helps (see below). none of the patients have reported sudden loss of consciousness or cardiac arrythmias as is rarely seen in some cases of glossopharyngeal neuralgia (so called vago-glossopharyngeal neuralgia). none of the patients have reported gastrointestinal parasympathetic symptomatology such as abdominal pain or diarrhea. there is one case report in the literature with a patient reporting episodic diarrhea and abdominal pain that was cured following microvascular decompression of the vagus nerve.
