The above diseases may have localized pressure pain, which is related to changes in body position, and the diagnosis can be confirmed by perfecting the corresponding X-ray film. In addition, it is also important to be aware of respiratory diseases, such as pneumonia and lung abscess, which may also cause back pain, and can be clarified by perfecting the CT of the lungs. Also, be alert for atypical angina pectoris, which often has some correlation with activity and exertion, and ST-T changes can be seen on the electrocardiogram.
