Thumb-Side Wrist Pain (De Quervain's Tenosynovitis): Symptoms, Causes & PT Treatment
Updated October 20261 minute read
De Quervain's tenosynovitis is irritation of the tendons on the thumb side of the wrist, causing pain there with gripping, lifting, wringing, or thumb movements. It's very common in new parents (from repeatedly lifting a baby) and with repetitive thumb use. It's not serious and responds well to activity changes, a thumb-and-wrist splint, and graded strengthening. Most people improve over several weeks.
What is De Quervain's tenosynovitis?
It's irritation and swelling of the sheath around the thumb-side wrist tendons, making thumb and wrist movements painful.
Symptoms
Common features are pain and tenderness on the thumb side of the wrist, worse with gripping, lifting, wringing, or moving the thumb, sometimes with swelling. Pain may travel up the forearm.
What causes it / risk factors
Repetitive thumb and wrist use (lifting a baby, texting, certain jobs and hobbies) and hormonal changes around pregnancy contribute.
How it's diagnosed
Diagnosis is clinical, often with a simple thumb-tuck test that reproduces the pain.
Physical therapy treatment
What a PT does. Your therapist offloads the tendons with splinting and activity changes, then restores motion and progressively strengthens. Exercises & progression (overview). A thumb-spica splint, activity modification, and graded tendon loading and strengthening. Recovery timeline. Many cases improve over several weeks with consistent care.
Treatment options compared
Splinting and conservative care are first-line. Injections help some stubborn cases; surgery is rarely needed.
Red flags
Seek care for a hot swollen wrist with fever, severe pain after an injury, or numbness suggesting nerve involvement.
