Rotator Cuff Tears: Signs, Symptoms & Treatment Guide

A sharp catch when reaching for a coffee cup may signal a rotator cuff tear, a common shoulder injury that disrupts sleep and daily tasks.

The rotator cuff is a sleeve of muscle that holds the arm bone in the shoulder socket. A partial tear frays like a rope; a full tear severs it completely. The Drop Arm test can help identify injury: lift the affected arm parallel to the floor, then lower it slowly. If your arm drops uncontrollably, structural damage may be present.

Seek immediate medical attention if you experience sudden loss of lifting strength, pain that prevents sleep, inability to reach behind your back, or a popping sensation during injury.

Doctors distinguish between shoulder bursitis and rotator cuff tears using MRI imaging. The supraspinatus tendon, which raises the arm, frequently experiences friction and tears when tissues pinch in the shoulder's tight subacromial space.

Most rotator cuff tears heal without surgery. Physical therapy progresses through three stages: pain reduction, range of motion exercises, and strengthening work. Corticosteroid injections reduce swelling when exercise alone fails. Regenerative medicine uses the body's own cells to stimulate repair. Surgery becomes necessary when conservative treatment fails and overhead lifting remains weak. Post-surgery physical therapy focuses on gentle movement to prevent scar tissue.

Prevent injury by sleeping on your back or placing a firm pillow under your armpit if you sleep on your side. Avoid repetitive overhead reaching. Resistance band exercises—internal rotation, external rotation, and scapular squeezes—build long-term shoulder stability.
