De Quervain’s Tenosynovitis

Pain on the thumb side of the wrist when you grip, pinch, lift or twist. The thumb tendons are squeezed in their tunnel. Common in new parents. Rest, a splint and, if needed, an injection usually sort it.

Typical signs: pain and sometimes swelling at the base of the thumb and side of the wrist, worse lifting a baby, opening jars, wringing or texting. There may be creaking or catching as the thumb moves.

Why it happens: the two tendons that move the thumb get irritated where they run through a tight tunnel at the wrist. It’s about 3 times more common in women and often follows pregnancy and the early months of lifting and feeding a baby. Repetitive gripping with the wrist bent is another trigger. Often there’s no clear reason.

Diagnosis: from the story and simple thumb and wrist movement tests, such as tucking the thumb into a fist and tilting the wrist down. Scans or X-rays are rarely needed.

The thumb-side wrist pain ladder

Most people improve with load changes and a splint. A steroid injection is the best-tested next step.

  1. Step 1 · Self-careChange how you use the handLift with palms up and wrists straight, scoop the baby with your forearms, take breaks from gripping, texting and wringing.
    Works
    No trials, but it removes the trigger and many mild cases settle
    Cost

    How long
    Weeks
    Watch for
    Total immobilisation for months: stiff thumb, no thanks.

    Your thumb has been doing overtime. Give it some annual leave.

  2. Step 2 · PharmacyThumb splintA wrist-and-thumb (“thumb spica”) splint, especially for sleep and aggravating tasks.
    Works
    Weak evidence on its own, but cheap and low risk
    Cost
    About $25–60, or fitted by a hand therapist
    How long
    3–6 weeks
    Watch for
    Too tight: numbness or tingling. Loosen it.

    Ugly, unfashionable, effective-ish.

  3. Step 3 · PharmacySimple pain reliefParacetamol, anti-inflammatory gel or a short course of tablets.
    Works
    Little direct evidence; may take the edge off
    Cost
    About $5–20
    How long
    Short term
    Watch for
    Breastfeeding: check with your pharmacist which medicines are suitable (ibuprofen and paracetamol usually are).

    Comfort while the splint does its job.

  4. Step 4 · ProcedureSteroid (cortisone) injectionAn injection into the tendon sheath by a GP, hand surgeon or under ultrasound. Sometimes a second one is needed.
    Works
    In small trials, for every 2 people injected, about 1 more got better than with a splint alone
    Cost
    About $0–250 depending on the clinic; sometimes bulk-billed
    How long
    Works over days to weeks
    Watch for
    Skin thinning or lightening at the injection site; a short pain flare. Diabetes: blood sugar can rise for a few days.

    A small needle with a strong track record.

  5. Step 5 · Allied healthHand therapyA hand therapist (physio or OT) can make a custom splint and guide strengthening once pain settles.
    Works
    Helpful for splint fitting and return to tasks; limited trial data
    Cost
    About $90–130 a session; Medicare rebates with a GP care plan
    How long
    A few sessions
    Watch for
    Strengthening too early can flare it.

    Specialist help for a very specific problem.

  6. Step 6 · SpecialistSurgeryA small operation to open the tendon tunnel, for symptoms that persist despite injections.
    Works
    Only very occasionally needed; usually relieves symptoms
    Cost
    Free in the public system (expect a wait); private costs vary
    How long
    A few weeks of recovery
    Watch for
    Numbness from irritation of a small skin nerve; scar tenderness.

    The last rung. Most people never get there.

Costs are rough Australian prices in November 2026 and vary by pharmacy and provider. PBS co-payment: $25, or $7.70 with a concession card. Results are typical figures from trials, not promises.

Save your money

Popular, heavily marketed or often asked about, but the evidence is weak or says no.

What you can do

See your GP if

See a doctor the same day for a hot, red, swollen wrist, especially with fever or after a cut or bite, or wrist pain after a fall (a broken scaphoid bone can be missed on first look).

Common questions

Why do new parents get de Quervain’s?

It often follows pregnancy and the first year with a baby. Hormone changes and the constant lifting and feeding may both play a part. It usually settles as lifting changes and with treatment.

Is a steroid injection safe while breastfeeding?

Yes, a single local injection is generally considered compatible with breastfeeding. Ask your doctor if you have concerns.

How long does de Quervain’s last?

Mild cases can settle in weeks with rest and a splint. An injection usually helps within days to weeks. Persistent cases may need a second injection or, rarely, surgery.

Is it the same as arthritis at the base of the thumb?

No, although they hurt in a similar area. Thumb-base arthritis affects the joint itself and is more common in older people. Your GP can tell them apart.
