Thoracic spine will not cause chest tightness and shortness of breath, but thoracic spine small joint disorder, thoracic spine scoliosis, thoracic disc herniation may cause chest tightness and shortness of breath. 1. Thoracic spine small joint disorder: when the structure of the thoracic spine changes and the position of the small joints is interlocked or disorganized, activities will cause the disorganized joints to rub together and stimulate the intercostal nerves, thus causing chest tightness and shortness of breath. 2. Thoracic scoliosis: abnormal development of thoracic vertebrae will compress the respiratory organs around the thoracic vertebrae, thus affecting the normal respiratory function of the human body, which may lead to the phenomenon of chest tightness and shortness of breath. 3. Thoracic disc herniation: chronic strain or degenerative changes in the thoracic spine can cause the nucleus pulposus of the intervertebral disc to protrude into the annulus fibrosus, which can compress the surrounding nerve roots and cause chest tightness and shortness of breath. When the phenomenon of chest tightness and shortness of breath occurs in the body, it is necessary to pay attention to it and go to the hospital in time.
