Thoracic spine compression of nerves generally refers to compression of the T1-T12 nerves in the thoracic spinal segments. There are 12 pairs of thoracic nerves emanating from the thoracic segment of the spinal cord, all with anterior and posterior branches. The anterior branches, with the exception of the first thoracic nerve, are not clustered and are called intercostal nerves, while the posterior branches innervate the back posteriorly. The sympathetic nerves of the thoracic segment travel with the spinal nerves and are called visceral nerves, regulating and directing the activities of the internal organs. The thoracic nerves are divided into upper, middle and lower sections. Upper T1-T4 thoracic cardiac nerve: responsible for the heart and lungs. Compression of this segment can cause symptoms of the heart, trachea, and lungs, manifesting as tightness in the chest, palpitations (accelerated heartbeat, often accompanied by panic), and dyspnea. Middle T5-T8 large visceral nerve: responsible for the liver, stomach, gallbladder and small intestine, compression of this segment can cause digestive disorders; lower T9-T12 middle visceral nerve: responsible for the kidneys, large intestine, bladder, etc., and compression of this segment can have symptoms such as oedema, frequent urination, and so on. If the above symptoms occur, it is recommended to go to the hospital in time for early and regular treatment.
