How long does a cortisone injection take to work for de Quervain's tenosynovitis?

The medicine is placed near the irritated tendon coverings on the thumb side of the wrist. Reduced pain can make gripping and thumb movement easier, but repeated lifting, pinching, or wrist deviation can continue to irritate the area. A brief post-injection flare is possible. If symptoms persist, the clinician may check the tendon compartments, thumb movement, and whether another condition is contributing.

Use the thumb and wrist support, activity changes, and exercises recommended for you. Avoid testing the wrist with forceful gripping just because it feels better early on. Lift with the whole hand rather than a tight pinch when possible, and take breaks from repetitive thumb movements. Keep a note of swelling, grip pain, and daily tasks that remain difficult. Procedure guidance is available under [Cortisone Injection](/treatments/non-surgical-orthopedics/cortisone-injection/).

Contact the treating service if pain is severe or worsening, or if the injection site becomes increasingly red, swollen, or hot. Fever, drainage, or feeling unwell needs prompt assessment. Seek urgent help for breathing difficulty, facial swelling, or widespread hives. Arrange review for persistent weakness, reduced thumb movement, or pain that blocks ordinary use.

Ask how long to wear the support, which lifting tasks to avoid, and when hand therapy or another treatment should be considered.
