Causes include stress and anxiety. Other causes are not yet clear. The condition persists in the autonomic nervous system even when the original stress is relieved. An assumption in psychiatry is that a lack of serotonin can be associated with depression and anxiety. A further assumption is that a low levels of serotonin can causes spasms in the cervical area. A plausible explanation for the<unk> s is a lack of neurotransmitter preventing the central nervous system from detecting that the eosophagus is closed, so that the upper esophagus sphincter becomes, randomly, hypertonic. From this plot one can conclude that the virus is not causing the spasms, but well the stress induced by the situation. The condition can appear as a symptom of the generalized anxiety disorder. Early signs are other symptoms like difficulty or inability to eat (loss of appetite, satiety after swallowing minor quantities), headache, dry mouth at night, sleeping issues, tremor, tension in the neck, in the throat, abdominal, stomach or chest pain etc. The sequence can result from a recent stress, panic attack or worry. The subject heads to<unk> s when, for instance, eating pasty food requiring more throat cleanings, like peanuts, pumpkin seeds and other nuts, becomes painful. Continuous swallowing appears with the spasms as the brain interprets the feeling as something stuck. The vagus nerves seems to play a role in the mother condition through a neurovegetative hyperactivity or dysautonomia. It innerves the inferior pharyngeal constrictor muscle where the<unk> s occur. Throat spasms can also appear after an accident, a disease, may be caused or worsened by GERD. There may be hereditary factors. In the context of long covid psychiatrists envisioned a potential relationship with an immune reaction, involving cytokines, that would persist quietly. However, due the anxiogenic situation, stress was again present when the symptoms started.
