Understanding this injury
De Quervain's Tenosynovitis is an irritation of the two tendons that run along the thumb side of your wrist — the ones you use every time you lift, pinch, grip, or twist your thumb away from your fingers. When the sheath around these tendons swells, even small movements like opening a jar or picking up your child can send a sharp pain shooting up the wrist.
It's so common in new parents that it's often nicknamed 'mommy thumb' or 'mommy wrist' — repeatedly scooping up a baby is the perfect mechanism. The condition responds extremely well to physical therapy, and most people avoid the cortisone shots and surgery that used to be the default treatment.
Common symptoms
- Pain near the base of the thumb
- Swelling near the wrist
- Difficulty gripping or pinching
- A catching or snapping sensation when moving the thumb
What causes it
- Repeated lifting of a baby or toddler
- Phone scrolling and texting (texter's thumb)
- Racquet sports, golf, and gardening
- Hormonal changes during and after pregnancy
- Repetitive job tasks involving thumb grip
Who's most at risk
- New parents and caregivers of infants
- Women age 30-50 (especially postpartum)
- Workers who do repetitive thumb-side gripping
- Musicians, hairstylists, and dental hygienists
- Anyone with prior wrist injury or arthritis
How we treat it
Your PT will confirm the diagnosis with a quick Finkelstein test, then build a recovery plan around three goals: rest the irritated tendons, reduce inflammation, and rebuild capacity. We start with a custom thumb-spica splint that keeps the thumb still while letting the rest of your hand work normally. Combined with ice, gentle tendon glides, and soft-tissue work on the forearm, this usually quiets symptoms quickly.
From there we add eccentric loading, grip strengthening, and movement re-education so the tendons can handle daily life — including picking up your kids — without flaring up again. We'll also coach you through the small adjustments (how you hold your baby, your phone, your tools) that make the biggest difference long-term.
If your symptoms aren't improving in 2-3 weeks, are getting worse, or starting to limit daily activities, call us or schedule an appointment online today — early intervention almost always means a faster, fuller recovery.
Recovery timeline
Most patients feel significantly better in 3-6 weeks. Postpartum cases may take a bit longer because hormones still play a role, but full recovery in 6-10 weeks is the norm with consistent PT.
What you can do at home today
- Ice the thumb side of your wrist for 10 minutes, 2-3 times daily
- When lifting a baby, scoop with both forearms instead of thumbs-out
- Switch your phone to your non-dominant hand for a few weeks
- Avoid wringing motions (towels, jar lids) during the flare
- Wear your splint consistently — especially when sleeping
These tips support recovery but don't replace a professional evaluation. If you're unsure or symptoms worsen, please reach out.
When to call us right away
If pain becomes constant, you lose grip strength, or there's visible swelling and warmth on the thumb side of your wrist, get evaluated promptly so we can prevent it from becoming chronic.
