Does cortisone injection treat rotator cuff tear?

The rotator cuff is a group of tendons that helps stabilise and move the shoulder. A tear can cause pain, weakness, and discomfort when lifting the arm. Cortisone may reduce inflammation in the shoulder space and make movement more comfortable for a time. That symptom relief is different from healing the tendon. The clinician considers the tear's size and location, your strength, the injury's timing, and your activity needs before recommending an injection.

Have persistent shoulder pain or weakness assessed rather than relying on repeated injections. A plan may combine activity changes, pain relief, and physiotherapy to maintain motion and build useful shoulder strength. Avoid movements that sharply increase pain, but gentle movement can help prevent stiffness when advised. Discuss the diagnosis and options in [Rotator Cuff Tear](/conditions/rotator-cuff-tear/) and read about [Cortisone Injection](/treatments/non-surgical-orthopedics/cortisone-injection/).

Get prompt care after a fall or lifting injury if you suddenly cannot raise the arm, the shoulder looks deformed, or severe pain is accompanied by numbness or a cold hand. Contact a clinician quickly for fever, spreading redness, or increasing warmth after an injection, as these may signal infection.

How much of the tendon is torn? Is weakness coming from the tear or pain-related guarding? Could an injection interfere with a procedure I may need? Which exercises are safe now?
