Coughing at the base of the neck is a normal phenomenon.
Coughing is a deep inhalation after the vocal folds are closed and then sudden violent breathing, due to the vocal folds are closed, at this time, violent coughing is a kind of forceful exhalation movement, which causes the pressure in the thoracic cavity to increase, and affects the venous blood return in the chest, resulting in the venous pressure of the neck is elevated and expanded.
At the same time, the root of the neck is the supraclavicular fossa formed between the sternal notch and the left and right clavicles, which is mainly soft tissue, and the veins here are enlarged on the body surface, and the supraclavicular fossa itself undulates with the respiratory movement, so when coughing, it looks like the root of the neck is bulging from the outside.
In addition, it is necessary to exclude localized enlargement caused by other diseases of the neck, such as hyperthyroidism, cervical lymphadenitis, hypothyroidism, and so on.
If you find abnormalities at the base of the neck, it is recommended that you go to the hospital, complete the ultrasound of the thyroid gland, thyroid function and other tests to determine the cause of the disease, and follow the doctor’s instructions for treatment.
