De Quervain's tenosynovitis causes pain and tenderness on the thumb side of the wrist. The tendons that move the thumb pass through a narrow compartment, and swelling can make their movement painful.
Lifting, gripping, wringing and repeated thumb motion often bring out the symptoms, but the condition can also occur without an obvious change in activity.
What it feels like
- Pain over the thumb side of the wrist
- Tenderness that may extend toward the thumb or forearm
- Pain with lifting a child, opening a lid or moving the thumb across the palm
- Swelling, creaking or reduced thumb use because movement hurts
Evaluation
The diagnosis is usually clinical. Examination compares thumb and wrist motion, localises the tenderness and checks for arthritis, a wrist problem or another tendon condition. Imaging is used when the pattern is unclear or another cause is suspected.
Nonsurgical care
- A thumb-and-wrist splint that limits painful tendon movement
- Changing lifting and gripping technique while symptoms settle
- Hand therapy for motion, ergonomics and gradual strengthening
- An injection in selected cases after discussing benefits and risks
When release surgery is considered
If pain remains limiting despite nonsurgical care, releasing the tight tendon compartment may be discussed. The tendons are inspected and protected, and the return to activity is guided by healing and comfort.

Frequently asked questions
Is De Quervain’s caused by texting?
Any repetitive thumb or wrist activity can aggravate symptoms, but no single activity explains every case. Treatment focuses on the painful tendon compartment and the tasks that provoke it.
How long should I wear a brace?
The useful duration depends on the severity and response. A brace is usually combined with a plan for gradually restoring comfortable motion rather than worn indefinitely without reassessment.
