How effective is cortisone injection for hand osteoarthritis?

A cortisone injection can sometimes ease pain and swelling in a hand osteoarthritis joint, but the benefit is variable and does not reverse joint changes. It may be considered when one clearly identified joint is interfering with gripping, pinching, or sleep. It should sit within a plan that also protects movement and hand function.

Hand osteoarthritis can affect the small joints at the fingertips, middle fingers, or thumb base. Injection targets irritation in a selected joint; it does not rebuild cartilage, correct a long-standing deformity, or treat every painful area at once. Improvement in pain may help you use the hand more comfortably, while stiffness or reduced strength can remain. A careful examination helps distinguish joint pain from tendon or nerve problems.

Before treatment, tell your clinician about diabetes, blood-thinning medicines, skin problems, and earlier injections. Afterward, follow advice on resting the hand and gradually resuming use. Gentle prescribed movement can help prevent guarding, while a splint or adapted grip may reduce strain. Track which tasks improve, such as opening a jar or writing, rather than judging the result only by a single painful moment.

Seek prompt medical advice if the finger or thumb becomes hot, increasingly red, very swollen, or more painful after the injection, particularly with fever or feeling unwell. Get urgent help for sudden loss of movement, new numbness or weakness, a cold or pale finger, or an injury. Book follow-up when symptoms continue, spread to other joints, or interfere with daily tasks despite the plan.

Ask which joint is the likely pain source, what improvement is realistic, and whether a splint, hand therapy, or activity modification should come first. Discuss aftercare, possible effects on blood glucose, repeat-treatment considerations, and how persistent deformity or weakness would be managed.
