Activities that might extend the recovery time from a rotator cuff injury include sleeping on the injured side, keeping the shoulder completely immobilized, and doing activities that involve repetitive arm motions, according to Mayo Clinic. Physical labor and some sports may worsen a rotator cuff injury.
People who have a rotator cuff injury should not paint, perform carpentry or do other construction jobs that require physical labor, notes Mayo Clinic. Throwing a baseball, swinging a golf club or other arm-based sports should not be attempted until the injury is fully healed. The injured person should not immobilize the injury entirely, as immobilization can lead to a frozen shoulder, which is when the surrounding connective tissue becomes tight and thickened. People over the age of 40 are more likely to tear their rotator cuff.
Rotator cuff injuries can be caused by repetitive motions, states Mayo Clinic. Repeating the same motion may inflame the tendons and muscles surrounding the rotator cuff, which can lead to eventual tearing. Falling on the shoulder may cause a rotator cuff injury. It is possible to strain the muscle surrounding the rotator cuff by attempting to lift or pull something too heavy. An overgrown bone may cause damage and irritation to the rotator cuff. The most common symptom of a rotator cuff injury is a dull, aching pain. Some rotator cuff injuries may require physical therapy or surgery.
