De Quervain's Tenosynovitis: Thumb and Wrist Pain

De Quervain's tenosynovitis is irritation and swelling of the tendons that move the thumb along the thumb side of the wrist.

The tendons pass through a narrow covering near the wrist. When the covering becomes thickened or sensitive, thumb movement and gripping can hurt. The condition is sometimes called mummy thumb or mother's wrist, but it can affect anyone.

Thumb pain and wrist pain are very common presentations of De Quervain's tenosynovitis. Pain may spread along the thumb side of the forearm and become sharper when lifting a child, opening a jar, turning a key, or making a grasp. Swelling or tenderness near the base of the thumb can occur, and the area may feel creaky when the tendons move.

Pain with use does not identify the cause by itself; a fall, arthritis, or another tendon problem can produce similar symptoms, so persistent pain merits an examination.

Repeated thumb motion, forceful gripping, and wrist positions that load the thumb-side tendons can irritate their covering. Sudden changes in childcare, work, sport, crafts, or device use may expose the tendons to more activity than they can comfortably tolerate. Sometimes no single cause is found.

Symptoms may begin gradually or after a period of increased hand use. Without a change in the provoking load, pain can become more persistent and make ordinary gripping difficult. Improvement often follows a period of protection and graded movement, although the pace varies with tendon irritation and daily demands.

Risk factors include repetitive thumb use, frequent lifting with the wrist angled, forceful pinching, and a recent increase in manual tasks. Pregnancy and the period after childbirth can coincide with symptoms, partly because caring for an infant involves repeated lifting and awkward thumb positions.

Diagnosis usually starts with the location and behaviour of pain, followed by examination of thumb and wrist movement, tenderness, swelling, and grip. A clinician may use a thumb-and-wrist movement test to reproduce tendon pain. Imaging is not always needed, but ultrasound or another scan may help when the diagnosis is uncertain or another wrist problem is suspected.

Care aims to calm tendon irritation while preserving useful hand movement. A splint can rest the thumb and wrist during aggravating activities. Hand therapy can adjust grip and lifting technique, guide gentle mobility, and build strength as pain settles. A cortisone injection may be considered for ongoing symptoms. If symptoms remain limiting despite appropriate non-surgical care, De Quervain's release can create more space for the tendons.

Hold heavier items with both hands, keep the wrist neutral when lifting, and use the palm rather than a pinching thumb when possible. Shorter activity periods with breaks may be easier than one prolonged session. A therapist can adapt baby-care, work, kitchen, or hobby tasks to reduce strain.

Ongoing irritation can restrict thumb movement, reduce grip confidence, and make daily tasks harder. Overprotecting the hand for too long can also leave it stiff or weak, so recovery plans generally progress from protection to comfortable movement and gradual loading.

Increase repetitive hand tasks gradually, vary how you grip and lift, and keep the wrist aligned with the forearm. Take breaks during sustained thumb work and address early pain before it changes how you use the whole hand.

An orthopedic clinician, hand surgeon, or hand therapist can assess pain at the thumb-side wrist. Describe recent changes in lifting, work, sport, childcare, or device use and mention which movements reproduce the pain.
