Does cortisone injection treat shoulder osteoarthritis?

Shoulder osteoarthritis involves changes in the joint surfaces and surrounding tissues. It can cause aching, stiffness, and pain when reaching or rotating the arm. Cortisone placed into the joint may reduce inflammation and make movement more comfortable. The benefit can vary, and an injection is symptom management rather than a restoration of cartilage. Assessment also helps identify whether pain comes from the main shoulder joint or another nearby structure.

Arrange a review if stiffness is worsening or ordinary tasks are becoming difficult. Care may include tailored exercises to preserve movement and strength, pacing activities, and other pain strategies. If an injection is discussed, tell the clinician about diabetes, blood-thinning medicine, allergies, and previous injections.

Get urgent help for a suddenly hot and swollen shoulder with fever, severe pain after an injury, or a new inability to move the arm. Following an injection, promptly report spreading redness, discharge, fever, or pain that is rapidly intensifying.

Which shoulder joint is causing the pain? What improvement should I reasonably look for? How can exercise protect my movement? What alternatives are available if symptoms continue?
