The short answer
De Quervain's tenosynovitis affects tendons on the thumb side of the wrist and can make gripping or lifting painful. Assessment helps distinguish it from arthritis, injury and other wrist conditions before choosing treatment.
Understanding the problem
Pain can occur near the base of the thumb and may travel into the forearm. Swelling or difficulty moving the thumb can accompany it. Repeatedly performing a painful self-test is not needed to prove the diagnosis.
Care and next steps
Activity changes, a suitable splint and symptom-relief measures may be discussed. A clinician may consider an injection or surgery in selected cases. The choice depends on symptoms, examination and response to earlier care.
Prepare for your consultation
Describe which daily tasks provoke pain, including lifting a child, carrying bags or repetitive work. Bring any brace you already use so the fit can be checked. Ask how to adapt the specific task that matters most to you rather than trying to avoid all hand use. If a procedure is proposed, discuss its expected benefit, risks and aftercare.
Common questions
Is thumb-side wrist pain always de Quervain's?
No. Examination is needed because several conditions can cause pain in that area.
