When is cortisone injection recommended for thumb arthritis?

Thumb arthritis commonly affects the joint at the base of the thumb, where gripping and pinching place substantial load. It can cause aching, tenderness, stiffness, and reduced hand strength. Cortisone is placed into or near the painful joint to reduce inflammation. It may ease symptoms for a period, but it does not reverse cartilage wear or change the shape of the joint. The decision depends on examination and the effect on daily tasks.

Try the measures recommended for your hand, such as a thumb splint, pacing painful tasks, adapting jar opening or gripping, hand exercises, and suitable pain relief. Tell the clinician about diabetes, skin infection, blood-thinning medicine, allergies, and previous injections. If an injection is given, protect the hand as advised and build activity back gradually. A review is useful if pain persists, grip declines, or splinting no longer allows ordinary tasks.

Seek prompt care for sudden severe pain after injury, a visibly deformed thumb, inability to move it, new numbness, or a hot swollen joint with fever. After injection, urgent advice is needed for increasing warmth, redness, swelling, drainage, fever, or rapidly intensifying pain.

Ask which thumb joint is involved, what improvement to expect, how long to use a splint, how hand therapy will continue, and what options remain if symptoms return.
