Back pain may involve orthopedics, thoracic surgery, cardiology, psychiatry, etc. If the back pain is related to postural changes, local pressure on bones, etc., it may be caused by cervical spondylosis, thoracic spondylosis, and other orthopedic diseases, and further consultation with orthopedics is required. It may also be caused by lung diseases, such as lung abscess, pneumonia, etc., and can be further treated by respiratory and thoracic surgery. Of course, angina pectoris may also manifest as pain in the back, and if the pain is related to activity and lasts for a few minutes to half an hour, the patient may be seen by a cardiologist. Of course, there are also patients who suffer from psychological factors, such as anxiety and depression, that require psychiatric treatment.
