What Is the First Treatment for Shoulder Osteoarthritis?

Shoulder osteoarthritis involves gradual changes in the joint surfaces that can make movement painful or limited. Initial care focuses on maintaining useful motion without repeatedly irritating the joint. A clinician may tailor pain relief, advise on load and sleep positions, and refer you for [Physiotherapy](/treatments/physiotherapy-and-rehabilitation/physiotherapy/).

Rehabilitation may include gentle mobility work, strength for the shoulder and upper back, and practical ways to manage dressing, reaching or lifting. Improvement is judged by function and comfort, not by forcing the joint through pain.

Use the shoulder within a comfortable range and break demanding tasks into smaller parts. Avoid repeatedly lifting through sharp pain, but do not keep the arm completely still unless a clinician tells you to. Bring a list of medicines and any conditions that could affect pain-relief choices to your appointment.

If symptoms remain limiting, an injection may be discussed as a time-limited way to reduce joint inflammation and support movement; see [Cortisone Injection](/treatments/non-surgical-orthopedics/cortisone-injection/). When non-surgical care no longer provides useful function, [Shoulder Replacement](/treatments/joint-replacement/shoulder-replacement/) may be considered after specialist assessment.

Seek urgent assessment after a major injury if the shoulder is visibly deformed, suddenly unusable, or accompanied by numbness or a cold hand. Arrange a routine review for steadily worsening pain, increasing stiffness, swelling, fever, or difficulty with essential daily tasks.

Ask which activities should be modified, what range of motion is a safe target, and how progress will be measured. Discuss whether an injection is suitable for you and what findings would support considering shoulder replacement.
