Maggie Beer CBD Gummies How do I recognize if my pain is associated with rotator cuff damage? It can be very hard to explain pain within the cuff. It might also exist simply as a dull pain. Yet even such mild pain may be symptomatic of the onset of impingement. Impingement, through the years, can turn into a complete-blown tear. Pain from early onset impingement usually only occurs all through exertion of the arm, specifically if this has involved raising the arm overhead.
