Is your thumb-side wrist painful — especially when you pinch or lift things?
De Quervain’s Tenosynovitis — inflammation of the tendon sheath around your thumb tendons.
Wrist pain on the thumb side after carrying a baby or extended smartphone use? If Finkelstein’s test causes sharp pain, De Quervain’s tenosynovitis is a strong possibility.
Quick Answer: De Quervain’s tenosynovitis is inflammation of the tendon sheath surrounding the two thumb tendons (abductor pollicis longus and extensor pollicis brevis). Finkelstein’s test (bending the wrist toward the little finger with the thumb tucked inside the fist) is positive when it causes sharp pain on the thumb side. The key is to calm the sheath inflammation (Calm Down), restore thumb and wrist movement balance (Wake Up), and correct repetitive movement patterns (Connect).
Seek medical attention quickly if:
- Fever, redness, and significant warmth in the wrist → rule out septic tenosynovitis immediately
- Wrist deformity or severe swelling after trauma → rule out fracture
- Sudden loss of thumb movement or numbness
3 Key Points on This Page
- Typical symptoms of De Quervain’s and how to self-check
- Why it develops — thumb overload and nervous system sensitivity
- How the 3-stage Circulation Therapy restores recovery
These symptoms suggest De Quervain’s tenosynovitis
- Pain and tenderness on the thumb side of the wrist (radial side) — Pressing the outer wrist near the thumb base hurts.
- Pain worsens when moving the thumb or gripping — Opening jars, using chopsticks, and scrolling on a phone become painful.
- Worsens after repetitive thumb use — Carrying a baby, extended smartphone or keyboard use aggravate symptoms.
- Warm, swollen feeling at the wrist — The area may feel warm and puffy.
- May be worse in the morning — First movements after sleep can bring sharp pain.
Why does De Quervain’s develop?
The two thumb tendons (abductor pollicis longus and extensor pollicis brevis) pass through a narrow tunnel over the wrist bone. Repetitive overload (Load) causes the surrounding tendon sheath to thicken and become inflamed, producing pain.
Key triggers include:
- Postpartum childcare — Repeatedly lifting and lowering a baby overloads the thumb and wrist.
- Extended smartphone use — Repeated thumb scrolling and typing accumulates load on the tendons.
- Keyboard and mouse use — Holding the wrist in a fixed position while repeatedly using the thumb increases risk.
- Elevated nervous system sensitivity (Alarm) — Sleep deprivation, stress, and postpartum hormonal changes amplify pain.
Self-Test: Finkelstein’s Test
- Wrap your fingers around your thumb to make a fist
- Bend your wrist down toward your little finger
- Positive if sharp pain occurs on the thumb side of the wrist

Our Approach at Yonsei SM Pain Clinic
De Quervain’s tenosynovitis requires reducing tendon sheath inflammation and correcting thumb and wrist use patterns.
- Phase 1: Calm Down (Circulation HD)
Ultrasound-guided hydrodissection targets inflammation and swelling around the tendon sheath. We create space in the narrowed sheath tunnel to relieve pain. - Phase 2: Wake Up (Circulation PT)
We restore balance in wrist and thumb muscles — abductor strengthening, forearm stretching, and wrist stabilization training. - Phase 3: Connect
We correct baby-holding posture, smartphone grip technique, and keyboard habits. Movement patterns are restructured to prevent recurrence in daily life.
De Quervain’s Self-Care
What You Can Do Now
- Wear a thumb spica splint for support
- Change how you lift and hold your baby
- Use both hands when using your smartphone
- Warm compress (2–3 times daily, 15–20 min) to improve circulation
- Temporarily reduce pain-provoking movements
What to Avoid
- Forced thumb stretching during acute flare-ups
- Pushing through pain and continuing to use the thumb
- Lifting a baby with one hand only
- Extended keyboard use with wrist in a bent position
If pain worsens suddenly with fever and redness, septic tenosynovitis cannot be ruled out. Seek medical attention immediately.
Frequently Asked Questions
How is De Quervain’s different from carpal tunnel syndrome?
De Quervain’s causes pain on the thumb side of the wrist with a positive Finkelstein’s test. Carpal tunnel syndrome involves compression of the median nerve on the palm side, causing numbness in the thumb, index, and middle fingers. Both can coexist and need individual assessment. Carpal Tunnel Syndrome →
Why is De Quervain’s so common after childbirth?
The combination of repeatedly lifting a baby, nursing postures, sleep deprivation, and postpartum hormonal changes creates a perfect storm of tendon overload and heightened nervous system sensitivity. It is especially common in women in the weeks after delivery. Wrist Pain Q&A →
Can a splint alone resolve it?
In mild early cases, splinting combined with movement corrections can lead to improvement. However, if pain persists or recurs, treating the underlying sheath inflammation directly is needed. Circulation HD →
How long does treatment take?
Recovery depends on how long symptoms have been present and their severity. We follow a Calm Down → Wake Up → Connect sequence. Correcting movement patterns after pain resolves remains important to prevent recurrence. Treatment Duration Q&A →
Does the whole arm need to be assessed?
Thumb-side wrist pain can sometimes overlap with referred pain from the neck or shoulder. Gait analysis and movement assessment help identify where pain originates. What is Gait Analysis? →
