A rotator cuff tear can extend or get larger over time. This can occur with repetitive use or a re-injury. It is common for patients with known rotator cuff disease to have acute pain and weakness following a minor injury. This likely represents extension of an existing tear. If you know you have a rotator cuff tear, then worsening pain and decreasing strength may mean the tear is getting larger.

Religion, however, is not the same as culture or ethnicity; it can overlap either. Technically, religion is defined as a set of beliefs. But while some religions confine themselves to the realm of ideas or beliefs, other religions extend into the realm of behavior and prohibit or mandate certain actions as well.
