De Quervain’s Tenosynovitis: Thumb and Wrist Pain Explained

Your baby is six weeks old, and every time you lift her out of the cradle a sharp pain shoots from the base of your thumb up the side of your wrist. Wringing out a cloth hurts. Opening a pickle jar is suddenly impossible. Or perhaps you are not a new mother at all: you spend hours texting, rolling chapatis, chopping vegetables or stitching blouses, and the thumb side of your wrist has started to ache and swell. Many people put up with this for months, thinking it is a sprain that will pass.

Very often, this pattern is De Quervain’s tenosynovitis. In this guide, our pain specialists explain what it is, why it is so common in new mothers and heavy phone users, a gentle self-check you can try, how it differs from other causes of thumb and wrist pain, and how it is treated, usually without surgery and without steroids.

What is De Quervain’s tenosynovitis?

Two tendons run along the thumb side of your wrist to move your thumb outwards and backwards. They are called abductor pollicis longus and extensor pollicis brevis, but you only need to know that they share one narrow tunnel, a sheath of tissue lined with a slippery layer, just above the bony bump on the thumb side of the wrist.

When those tendons are overworked, the sheath becomes irritated and thickens. The tunnel gets tighter, the tendons rub instead of gliding, and every movement of the thumb pulls on a sore spot. “Teno” means tendon and “synovitis” refers to irritation of the lining. Under a microscope, long-standing cases show thickening and wear more than true inflammation, which is one reason anti-inflammatory tablets alone often disappoint.

It is one of the commonest causes of pain on the thumb side of the wrist, and it sits in our wider guide to wrist pain and carpal tunnel syndrome.

What does it feel like?

• Pain over the thumb side of the wrist, sometimes spreading up the forearm or into the thumb.
• Pain that flares with gripping, pinching, lifting a kettle, wringing clothes or twisting jar lids and taps.
• A small, tender swelling just above the wrist on the thumb side.
• A catching or creaking feeling when you move the thumb.
• Weak grip, so you drop things or avoid using that hand.

Why is it so common in new mothers and phone users?

Anything that keeps the thumb stretched out while the wrist bends sideways, again and again, loads this tunnel. The usual culprits in our clinics are:

• New mothers (“mommy thumb”). Lifting a baby under the armpits with the thumbs spread wide, dozens of times a day, is the classic trigger. Night feeds and poor sleep make recovery slower.
• Pregnancy and hormonal changes. Fluid retention and hormone shifts during pregnancy and breastfeeding seem to make tendon sheaths more sensitive. The same changes are behind problems such as sciatica in pregnancy.
• Smartphone use. Texting and scrolling with one thumb for hours keeps the tendons working in a cramped position. The same habit often brings neck pain from long screen hours.
• Kitchen and home work. Rolling chapatis, grating coconut, chopping, wringing clothes and carrying heavy shopping bags.
• Hobbies and trades. Gardening with secateurs, tailoring, embroidery, hairdressing, racquet sports and lifting weights.
• Women aged 30 to 50, and people with conditions that affect tendons and joints, such as diabetes or rheumatoid arthritis.

Overuse rarely stops at one tendon. Many of our patients with De Quervain’s also have elbow trouble from the same gripping habits, which we explain in golfer’s elbow vs tennis elbow.

Is there a simple self-check for De Quervain’s?

Doctors use a gentle stretch, often called the Finkelstein test, to stress these two tendons. You can try a mild version at home. Go slowly and stop at the first sign of sharp pain; the aim is to notice, not to push.

1. Rest your forearm on a table with the thumb side facing up.
2. Tuck your thumb gently into your palm and curl your fingers loosely over it.
3. Very slowly tilt your wrist down towards your little finger.

If this brings on a familiar pain over the thumb side of the wrist, while the other hand feels only a mild stretch, De Quervain’s is likely. It is a clue, not a diagnosis. Thumb arthritis and some wrist injuries can also hurt with this movement, so a proper examination still matters.

How is it different from other thumb and wrist problems?

Several conditions cause pain in the same small area. The table below shows the clues our doctors look for.

Pain in many small joints, especially with swelling and morning joint stiffness lasting more than half an hour, points towards an inflammatory arthritis rather than a single irritated tendon. Our guide on pain in many joints: osteoarthritis or rheumatoid arthritis explains the difference. Tingling that runs from the neck down the arm may come from a pinched nerve in the neck instead.

How is De Quervain’s treated without surgery?

Most people improve with a sensible combination of rest for the tendons, smarter habits and guided exercise. The earlier you start, the quicker it usually settles.

A thumb spica splint

This is a splint that holds the wrist straight and keeps the thumb still while leaving the fingers free. Worn during heavy activities and at night for a few weeks, it gives the sheath a chance to calm down. It should feel snug, not tight.

Changing how you lift your baby

Instead of lifting under the armpits with your thumbs spread, scoop your baby up with your whole hands: one palm under the bottom, the other supporting the head and neck, and bring the baby close to your chest. Use pillows to support your arms during feeds, and let family members share the lifting when they can. This single change often makes the biggest difference.

Phone and grip habits

• Hold the phone in one hand and type with the index finger of the other, or use voice typing.
• Use thicker handles on knives, ladles and garden tools so you do not pinch so hard.
• Carry shopping bags over the forearm rather than hanging them from your fingers.
• Use a jar opener, and keep the wrist straight when wringing clothes or rolling dough.

Ice, heat and exercises

Ice wrapped in a cloth for 10 to 15 minutes helps when the wrist is swollen and sore after use. Some people prefer gentle warmth before exercises once the acute flare settles. Start with tendon gliding: slow, pain-free thumb circles and bending the thumb across the palm, a few times a day. When these are comfortable, a physiotherapist adds strengthening with a soft ball or rubber band. Rushing to strengthen a still-angry tendon usually sets you back.

Painkillers can take the edge off for a few days, but they do not fix the overload, and long courses have their own risks. We explain why in living with chronic pain: why painkillers are not the answer.

What about steroid injections and surgery?

A steroid injection into the tendon sheath is commonly offered elsewhere for De Quervain’s. It can reduce pain for a while, and some people get lasting relief. It is not risk-free, though. Around the wrist, where the skin is thin, steroids can cause thinning and lightening of the skin, a dent from fat loss, and weakening of the tendon itself, especially after repeated injections. They may also raise blood sugar for a few days in people with diabetes. Read more in our guide to steroid side effects from repeated injections.

Surgery, called a De Quervain’s release, opens the tight sheath to give the tendons room. It is a relatively small operation and can help when months of proper treatment have not worked. We will say so honestly if we think you need it. Because most people recover without it, though, it should not be the first step, and a second opinion before surgery or injections is always reasonable.

Is treatment safe if I am breastfeeding?

This is one of the first questions new mothers ask us. Splints, habit changes, ice and exercises are all safe. When an injection is needed, the regenerative medicine we use at Dr Heal is prepared by Dr Heal Pharma and contains no steroids, painkillers or antibiotics, which many mothers find reassuring. Please always tell the doctor that you are breastfeeding, and mention any medicines or supplements you are taking, so that your care can be planned around you and your baby.

How Dr Heal treats De Quervain’s tenosynovitis

At our wrist and hand pain treatment clinics, we look beyond the sore tendon to the reasons it was overloaded in the first place.

1. Careful history and examination. One of our pain specialists asks about baby care, work, phone use and hobbies, examines the thumb, wrist, elbow and neck, and separates De Quervain’s from thumb arthritis, sprains and nerve problems.
2. Tests only when they help. An ultrasound or X-ray, and blood tests for sugar, thyroid, inflammation and vitamins, can be done under one roof at our in-house laboratory and radiology.
3. Splinting and habit coaching. A properly fitted thumb splint and practical changes for lifting, feeding, cooking and texting.
4. Steroid-free injection when needed. For pain that persists, we may use our own regenerative medicine, made without steroids, painkillers or antibiotics, to support the tendon’s healing rather than simply dampen the pain.
5. Functional medicine and rehabilitation. Through functional medicine we check things that slow tendon healing, such as blood sugar, thyroid, sleep and vitamin D and B12 deficiency, then guide you through exercises until your grip is strong again.

We follow the same root-cause approach for other overuse problems of the upper limb, including the elbow conditions in our frozen shoulder and tennis elbow guide and at our shoulder and elbow pain treatment clinic. If several joints are involved, our joint pain and arthritis treatment team looks at the bigger picture.

What you can do at home

• Rest the thumb, not the whole body. Keep moving, but cut down on pinching and wringing for a few weeks.
• Wear the splint as advised, particularly at night and during baby care or kitchen work.
• Take short breaks every 20 to 30 minutes when typing, stitching or chopping.
• Eat well and sleep when you can. Protein, fruit, vegetables and enough water help tendons repair, and the ideas in our guide to diet and arthritis pain apply here too. Poor rest makes any pain feel louder, as explained in sleep and chronic pain.
• Do not ignore it for months. A tendon sheath that has been thickened for a long time takes longer to settle.

Frequently asked questions

How long does De Quervain’s take to heal?

With a splint, habit changes and exercises, many people feel clearly better within four to six weeks, although full strength can take a few months. Cases that have been ignored for a long time usually take longer.

Will “mommy thumb” go away on its own after my baby grows?

It often eases once the baby is heavier to carry differently, hormones settle and breastfeeding ends. Waiting can mean months of pain, though, so changing how you lift and wearing a splint early is better than simply putting up with it.

Can using my mobile phone cause De Quervain’s?

Long hours of one-thumbed texting and scrolling can bring it on or keep it going, especially alongside other gripping work. Switching hands, typing with a finger and using voice input all reduce the strain.

Is De Quervain’s the same as arthritis?

No. De Quervain’s affects the tendons and their sheath, while thumb base arthritis affects the joint surfaces. They can feel similar, so an examination, and sometimes an X-ray or ultrasound, helps tell them apart.

Do I need surgery for De Quervain’s?

Rarely. Most people improve with non-surgical care. A release operation is considered only when symptoms persist for months despite proper splinting, exercises and treatment.

Where can I get De Quervain’s treated in Bengaluru?
