Aging
Aging is a major risk factor for the development of joint and bone diseases. When you get aged, bone degeneration and other types of bone damages force the body to acquire more calcium in the blood to help repair some damaged regions, including shoulders. As a result, calcification or thickening of the affected areas would eventually cause shoulder impingement. Over time, this condition would trigger a loss of shoulder function and pain. This makes it much difficult to keep a normal life. Shoulder impingement is more often reported in those people who are over 50 years old, but it would still develop at any age stage. [2]
