Shoulder pain

Since the age of 40s and 50s, periarthritis of the shoulder of unknown cause has become more likely to occur, and it is called frozen shoulder. It is considered that the inflammation is difficult to heal because arteriosclerosis progresses with age and the blood flow around the shoulder joint becomes poor. In addition, people with a lack of exercise and diabetes are more likely to get frozen shoulders. It is possible that this is also more likely to occur in people with poor blood flow.
