When symptoms of stuffiness and suffocation in the back occur, one should consider whether the nerves in the back have been damaged or squeezed. For example, patients with disorders of the small joints of the thoracic spine may experience this particular back sensation, mainly because the intercostal nerves and other nerves in the back are squeezed by the deformation of the thoracic joints, resulting in abnormal sensations in the nerves. The abnormal sensation can be relieved by rest or appropriate back activities. If the above symptoms are not present, consider whether there is chronic soft tissue inflammation that leads to soft tissue adhesions in the back and possibly other symptoms of stiffness and tension in the back movement. If the particular sensation is not directly related to back movement, consider whether there is a lesion in the heart, or other internal organs such as the lungs, and a chest CT or other examination should be performed promptly.
