Common causes of right posterior scapular pain include muscle strain, cervical spondylosis, coronary heart disease, etc. 1. Muscle strain: for example, people who work for a long time at work, due to the back muscle tension caused by myofascial chronic aseptic inflammation, resulting in right posterior scapular pain. 2. Cervical spondylosis: due to the herniated intervertebral discs, or hyperplasia of the cervical spine tissue compression of the nerve root, the pain radiates to the scapular region, which can cause right posterior scapular pain. 3. Coronary heart disease: Some coronary heart diseases such as myocardial ischemia and myocardial infarction generally cause pain in the precordial area or the back of the sternum, and the pain can radiate to the right shoulder, causing right posterior scapular pain. Caused by right posterior scapular pain may also have other reasons, such as trauma, cholecystitis, frozen shoulder, etc. It is recommended to go to the hospital in a timely manner to improve the examination, to clarify the cause of the disease, and standardized treatment under the guidance of the doctor.
