What Causes It?
Age-related degeneration - As you age, the risk of a rotator cuff injury increases. Rotator cuff tears are most common in people older than 40.
Repetitive overhead arm motions - Athletes who regularly use overhead arm motions, such as baseball pitchers, archers, and tennis players, have a higher risk of rotator cuff injuries.
Occupational overuse - Jobs that require repetitive overhead arm motions, such as carpentry or painting, can damage the rotator cuff over time.
Heavy lifting - Regularly lifting heavy objects, especially overhead, can strain the rotator cuff muscles and tendons.
Poor posture or technique - Incorrect posture or improper form when exercising can place extra stress on the rotator cuff.
Sudden trauma - Falling on an outstretched arm or lifting something too heavy with a jerking motion can tear the rotator cuff.
Bone spurs - As we age, bone spurs (bony projections) often develop on the underside of the acromion bone. When we lift our arms, these spurs rub on the rotator cuff tendon, weakening it and making it more susceptible to tears.
Decreased blood supply - As we age, the blood supply to the rotator cuff tendons decreases, which can lead to slower healing and increased risk of degeneration.
Genetic factors - Some people may have a genetic predisposition to rotator cuff injuries.
Previous shoulder injuries - A history of shoulder dislocations or other shoulder injuries can increase the risk of rotator cuff injuries.
Signs & Symptoms
Shoulder pain - Pain at the top and outer side of the shoulder, especially when reaching overhead or behind your back.
Shoulder weakness - Difficulty lifting the arm or performing specific movements.
Limited range of motion - Trouble raising or rotating your arm.
Pain at rest and at night - Particularly when lying on the affected shoulder.
Crackling sensation (crepitus) - A crackling feeling when moving your shoulder in certain positions.
Arm weakness - Difficulty lifting objects or performing everyday tasks.
Pain radiating down the arm - Not just localized to the shoulder area.
Shoulder instability - Feeling like your shoulder might "pop out".
Disturbed sleep - Discomfort that prevents you from sleeping on the affected side.
Difficulty reaching behind your back - Such as when trying to zip up a dress or tuck in a shirt.
