De Quervain & Trigger Finger
De Quervain's tenosynovitis and trigger finger are the two most common tendon problems of the hand and wrist, and although they affect different tendons, they share the same underlying mechanism: a tendon that no longer glides smoothly through the snug tunnel, or sheath, that guides it. At Modern Physio we focus on understanding the root-cause of your problem & personalizing your treatment for lasting results.
Understanding De Quervain & Trigger Finger
De Quervain's tenosynovitis and trigger finger are the two most common tendon problems of the hand and wrist, and although they affect different tendons, they share the same underlying mechanism: a tendon that no longer glides smoothly through the snug tunnel, or sheath, that guides it. In De Quervain's, the affected tendons are the two that move the thumb outwards and upwards, where they pass through a tight compartment on the thumb side of the wrist. When the sheath thickens, every thumb movement and every grip becomes sharply painful at that spot. The classic sufferer is a new parent — the condition is often called 'mummy thumb' — because lifting a baby many times a day, with the thumbs splayed under the arms and the wrist bent, loads exactly these tendons; it also appears with heavy phone texting, kitchen work, and repetitive gripping jobs. In trigger finger, the thickening affects the tunnel system on the palm side of a finger or thumb. A nodule forms on the flexor tendon and catches at the mouth of the first pulley of the tunnel, so the finger bends normally but then sticks, straightening suddenly with a snap or click — the 'triggering' — and in advanced cases can lock bent altogether. Both conditions are diagnosed clinically, without scans in most cases, and both respond to a stepped approach: activity and technique modification, splinting to rest the affected tunnel, and graded exercise as symptoms settle. Honesty matters here: when triggering is frequent or a digit locks, or when De Quervain's persists despite good conservative care, a corticosteroid injection — and occasionally a small release surgery — has strong evidence and we will say so and refer you. At Modern Physio in Jaipur, we manage the conservative side thoroughly and coordinate with hand specialists for the rest. Physiotherapy cannot dissolve a tendon nodule or an established sheath thickening, but it can settle irritation, correct the habits that caused the overload, and restore comfortable use of the hand.
Common Symptoms
- Sharp pain on the thumb side of the wrist with gripping, lifting, wringing clothes, or turning the thumb — the hallmark of De Quervain's
- Pain that shoots up the forearm or into the thumb when lifting a baby or a heavy pan with the thumbs spread wide
- Swelling or a tender thickened area over the thumb side of the wrist, sometimes with a small fluid-filled bump
- A catching, clicking, or snapping sensation when bending or straightening a finger or thumb — the hallmark of trigger finger
- A finger that sticks in a bent position and then releases suddenly, or in later stages must be straightened with the other hand
- A tender nodule or pea-like lump in the palm at the base of the affected finger
- Stiffness and triggering that are worst first thing in the morning and ease somewhat as the hand warms up
- Weak or painful grip, with objects such as jars, door handles, and utensils becoming difficult
- Pain on movements combining thumb tuck and wrist bend, such as pouring from a kettle or opening a two-wheeler throttle
- In advanced trigger finger, a digit locked in the bent position that no longer straightens fully
How Common Is It?
Both conditions are everyday presentations in hand and physiotherapy clinics. De Quervain's tenosynovitis is seen predominantly in women, with a striking cluster in the months after childbirth — 'mummy thumb' is common enough among new parents in Jaipur that many arrive having self-diagnosed from the internet — and also among heavy phone users and kitchen and manual workers. Trigger finger occurs most often in the ring finger and thumb of adults in middle age and later, is more common in women, and is considerably more frequent and often more stubborn in people with diabetes, where multiple digits may be involved.
Causes & Risk Factors
- Repetitive lifting of a baby with the thumbs splayed and wrists bent — the reason De Quervain's is so common in new mothers and grandmothers who share childcare
- Hormonal and fluid changes during late pregnancy and after delivery, which make the tendon sheaths more vulnerable in this period
- Repetitive gripping and wringing work in the kitchen and home, such as kneading dough and wringing clothes
- Prolonged smartphone texting and gaming with the thumbs, and heavy mouse or tool use at work
- Occupations and hobbies with sustained forceful grip — tailoring, gardening, carpentry, racquet sports, and two-wheeler riding
- Repetitive finger flexion under load, which is the typical driver of trigger finger in manual and desk workers alike
- Diabetes, which markedly increases the risk of trigger finger, and can make it affect several fingers
- Rheumatoid arthritis and other inflammatory conditions affecting the tendon sheaths
- Age and sex-related susceptibility, with both conditions more common in women and trigger finger most frequent in middle age and beyond
- Occasionally, direct pressure or a knock over the tendon tunnel that sets off local thickening
Our Diagnosis Process
- A history of your hand use — childcare, phone habits, kitchen and occupational tasks — to identify the repetitive load behind the problem
- For De Quervain's, palpation of the first extensor compartment on the thumb side of the wrist and a Finkelstein-type test, where tucking the thumb and bending the wrist reproduces the sharp pain
- For trigger finger, palpation of the palm at the base of the digit for a tender nodule, and observation of active bending and straightening to see and feel the catch or lock
- Grading of trigger finger severity — from painless clicking through painful catching to a locked digit — since the grade guides whether conservative care or injection referral is the right first step
- Assessment of grip strength, thumb and finger range of motion, and the practical tasks that are limited
- Screening for related conditions that change the picture, including diabetes, inflammatory arthritis, and pregnancy or recent delivery
- Differentiation from look-alike problems such as thumb-base arthritis, wrist ganglions, carpal tunnel syndrome, and nerve-related pain, which need different management
- Referral to a doctor or hand specialist when a digit is locked, triggering is frequent and disabling, symptoms persist despite good conservative care, or there is suspicion of infection or inflammatory disease
Our Treatment Approach
- Activity and technique modification as the first step — changing how the hand is loaded is the single most important intervention, since the sheath cannot settle while the aggravating pattern continues
- For new parents with De Quervain's, specific coaching in baby-lifting technique: scooping under the baby's bottom with the forearms and keeping the wrists straight, rather than gripping under the arms with splayed thumbs
- Splinting for De Quervain's with a thumb spica splint that rests the affected tendons, worn as advised for a period and weaned as symptoms settle
- Splinting for trigger finger with a small splint that limits the digit's bend, typically worn at night, to stop the nodule repeatedly catching in the pulley
- Ice or heat for symptom relief, used simply and practically alongside the load changes
- Gentle tendon-gliding exercises within comfort, progressing as irritation settles, so the tendon moves through the sheath without repeated catching
- Graded strengthening of the thumb, grip, and forearm once pain allows, restoring capacity for childcare, kitchen, and work demands
- Soft tissue treatment of the overworked forearm muscles as an adjunct to comfort and function
- Ergonomic advice for phones, keyboards, and tools, reducing sustained thumb-heavy and grip-heavy positions
- Selective use of electrophysical modalities for pain relief as an adjunct, never as the main treatment
- Honest, criteria-based referral for corticosteroid injection — which has good evidence in both conditions, particularly trigger finger — when triggering is frequent, a digit locks, or De Quervain's is not settling with well-executed conservative care
- Post-injection or post-surgical rehabilitation where needed, restoring glide, strength, and confidence after a release procedure

Recovery & Prevention Tips
- Change the aggravating pattern first: no splint or exercise will work while the same thumb-splayed lift or heavy grip is repeated fifty times a day
- If you are a new parent, lift your baby by scooping with both forearms under the body, keeping wrists straight and thumbs alongside the fingers — and ask family members who share childcare to do the same
- Wear your splint as advised, including at night for trigger finger, and wean it gradually as symptoms settle rather than stopping abruptly
- Use voice typing or alternate fingers for heavy phone use, and take breaks from prolonged texting and scrolling
- In the kitchen, use lighter pans where possible, hold vessels with both hands, and pause repetitive tasks such as kneading and wringing during the painful phase
- Do your tendon-gliding exercises gently and often; forcing a triggering finger through repeated clicks irritates the nodule further
- Apply ice over the tender tunnel after heavy hand use, or warmth in the morning for stiffness, whichever settles your symptoms better
- If you have diabetes, keep your blood sugar well controlled, as this influences both the risk and the stubbornness of trigger finger
- Do not ignore a finger that has begun locking; earlier review gives more options and better results than waiting until it is fixed in a bent position
- After an injection or release surgery, complete the follow-up exercises, since restoring full glide and strength is what protects the result

Evidence & Sources
The NHS describes trigger finger and advises that treatment options include rest, splinting, corticosteroid injection, and surgery for persistent cases, with milder cases sometimes improving without invasive treatment.
NHS: Trigger fingerA Cochrane review found evidence that corticosteroid injection is effective for trigger finger in adults, supporting injection referral when conservative measures are not sufficient.
Cochrane Review CD005617: Corticosteroid injection for trigger finger in adultsA Cochrane review of corticosteroid injection for De Quervain's tenosynovitis found evidence of symptom relief from injection, one of the established options when splinting and activity modification do not settle the condition.
Cochrane Review CD005616: Corticosteroid injection for de Quervain's tenosynovitisThe NHS advises that tendon sheath problems (tenosynovitis) are managed initially with rest from aggravating activity, splinting where appropriate, and a gradual return to movement, with referral for further treatment if symptoms persist.

What is 'mummy thumb' and why did I get it after having a baby?
Mummy thumb is the everyday name for De Quervain's tenosynovitis in new parents. It develops because a baby is lifted dozens of times a day with a very particular grip — thumbs splayed under the arms, wrists bent — which loads the two thumb tendons exactly where they pass through a tight tunnel at the wrist. Hormonal and fluid changes after delivery make the tendon sheaths more vulnerable in this period, so the combination of a susceptible sheath and a brand-new repetitive load produces the classic sharp wrist pain. It affects fathers and grandparents who share lifting duties too, and it responds well to lifting-technique changes, splinting, and graded rehabilitation.
Why does my finger click and get stuck when I bend it?
Because the tendon that bends your finger has developed a small thickening or nodule, and the mouth of the tunnel it runs through has tightened. Each time you bend the finger, the nodule squeezes through the tunnel entrance; when you straighten, it catches and then pops through — the click and snap you feel. As the mismatch worsens, the finger can stick bent and need the other hand to release it. It is a mechanical problem of tendon and pulley, not arthritis of the joint, which is why treatment targets the tunnel: splinting, load change, and, when catching is frequent, an injection at the tunnel.
Will a splint really help, and how long do I wear it?
Splinting is a genuine treatment for both conditions, not just a comfort measure, because it stops the thousands of daily glide cycles that keep the thickened sheath irritated. For De Quervain's, a thumb spica splint is typically worn for several weeks during aggravating activities, sometimes more continuously at first, then weaned. For trigger finger, a small splint holding the base of the digit straighter is usually worn at night, often for six weeks or more. The splint works only alongside changed hand use — wearing it while continuing the same lifting or gripping pattern gives disappointing results.
Do I need a steroid injection, or can physiotherapy alone fix this?
It depends mainly on severity and duration. Mild and recent cases of both conditions often settle with activity modification, splinting, and graded exercise alone. But we will be straight with you about the evidence: for trigger finger that catches frequently or locks, corticosteroid injection has strong support and is often the most efficient next step, and persistent De Quervain's also responds well to injection when conservative care has genuinely been tried. Our approach is to run proper conservative management, and to refer you for an injection opinion without delay when your grade or progress says that is the better path — not to keep you in therapy indefinitely.
Should I see a doctor or a physiotherapist first for my hand or thumb pain?
For typical gradual-onset thumb-side wrist pain or a clicking finger, a physiotherapy assessment is a reasonable first step: both conditions are diagnosed clinically, and conservative care is the accepted starting point for most grades. See a doctor first if a finger is locked bent and cannot be straightened, if the hand or finger is hot, swollen, and severely painful — especially with fever, which can indicate infection and is an emergency — if you have significant injury, or if you have diabetes or rheumatoid arthritis with multiple digit involvement. We refer to hand specialists in Jaipur whenever the grade or the progress warrants it.
Will trigger finger or De Quervain's go away on its own?
Sometimes. Mild trigger finger can settle over months, and post-partum De Quervain's often improves as childcare loads change and hormonal factors settle — but 'wait and see' has a real cost when symptoms are moderate: continued catching keeps thickening the nodule, and a locked finger left long can develop joint stiffness that persists even after the tunnel is treated. Our advice is not to panic over mild, improving symptoms, but to seek assessment when pain limits daily tasks, when catching is frequent, or when anything locks — earlier treatment is simpler treatment.
Can I prevent this from coming back?
Largely, yes, because both conditions are driven by load patterns that can be changed. Keeping the retrained baby-lifting technique, breaking up long texting and gripping sessions, using two hands for heavy pans and buckets, and maintaining the grip and forearm strength you built in rehabilitation all reduce recurrence. If you have diabetes, good sugar control matters for trigger finger risk. Recurrences that do happen tend to respond faster when addressed early, so returning promptly at the first sign of the old pain is itself a prevention strategy.
When should I seek medical help urgently for a hand problem?
Seek urgent medical care if a finger or the hand becomes rapidly swollen, hot, red, and severely painful, particularly with fever or after a cut or puncture — infection in a tendon sheath is an emergency that can permanently damage the hand within days. Also seek prompt care for a finger held rigidly bent that is exquisitely painful to straighten, numbness or colour change in a digit, or any significant hand injury with deformity. These need a doctor or emergency department first, not a physiotherapy appointment.
