Sudden suffocation not on the day of crisis is a bad sign. Choking without foam is easier, since foam is formed only when the heart reaches such a degree of heat at which the action of the lungs and the abdominal obstruction ceases and they cannot evenly deliver air to the heart. If there is no tumor in the throat, then choking occurs only for very significant reasons; often, or rather, most often, it occurs as a result of a brain disease. In general, if during severe fevers there are severe sore throats, it means that death has dawned on the patient, since the heart, due to intense heat, requires a lot of air, and the air passages are blocked, and the heart burns, its nature is extremely upset, and it becomes incapable of life.
A bad sign is also a curvature of the neck, which makes it impossible to swallow. This happens either due to displacement of the vertebrae or from severe dryness, and there is nothing worse with fever. If the patient can only swallow with difficulty, this is also a bad symptom, just as the fact that he is choking on water and the water comes out through the nose, or constantly choking on saliva is not a good sign.
