Chest and back pain may be caused by fasciitis, cervical spondylosis, coronary angina and small joint misalignment of the thoracic spine. 1. Fasciitis: This disease is a non-specific inflammation that occurs in the myofascia, and patients will experience pain at the site of onset. 2. Cervical spondylosis: when patients have cervical spondylosis, due to cervical spondylosis compression to the nerve, thus causing the back pain symptoms. 3. Coronary angina: patients with coronary artery disease and angina pectoris are caused by insufficient blood supply to the myocardium, and the patients will have pain in the back and chest. 4. Dislocation of small joints of thoracic vertebrae: when the small joints of thoracic vertebrae are dislocated, they may compress the nerves in the back and intercostal nerves, which will cause back pain, and the nerves will radiate to the chest, which will cause pain in the back of the chest as well. When patients have back pain behind the chest, they should go to the hospital in time for appropriate examination to clarify the cause of the disease and actively accept the doctor’s treatment.
