The pain that accompanies caregivers

Holding the baby, changing diapers, breastfeeding, scrolling the phone with the thumb, carrying bags — all these movements depend on the thumb tendons that pass through a narrow tunnel in the wrist. When demand exceeds recovery capacity, these tendons inflame and every grip becomes painful. This condition — De Quervain's tenosynovitis \u2014 is só common in first-time mothers that it was historically called "mother's wrist."

The diagnosis is clinical: pain on the radial side of the wrist (thumb side) that worsens when holding objects with the thumb in opposition. Finkelstein's test \u2014 ulnar deviation of the wrist with the thumb flexed inside the closed fist \u2014 reproduces the pain. But beyond the tendinous inflammation, trigger points in the thumb extensors and forearm muscles frequently contribute to the intensity and chronicity of the pain. Medical acupuncture addresses both components.

How thumb overload generates wrist pain

  1. First dorsal compartment

    The tendons of the abductor pollicis longus and extensor pollicis brevis pass through a synovial sheath at the radial styloid process. Repetitive thumb gripping movements — holding the baby, scrolling the phone screen, wringing cloths — generate excessive friction in this sheath.

  2. Inflammation and thickening

    Repetitive friction causes tenosynovitis: inflammation of the synovial sheath with thickening of the retinacular pulley. This further compresses the tendons, creating a self-perpetuating cycle of friction-inflammation-compression.

  3. Trigger points in the thumb extensors

    The forearm muscles that move the thumb — extensor pollicis brevis, abductor pollicis longus, and extensor pollicis longus — develop trigger points in response to chronic overload. These points refer pain to the wrist and base of the thumb, amplifying the tendinous pain and making it difficult to distinguish between myofascial and tendinous pain.

  4. Brachioradialis component

    The brachioradialis, frequently overlooked, is overloaded by repetitive gripping and refers pain to the radial wrist. Trigger points in this muscle contribute to the pain and reduce grip strength, generating the sensation of "weak wrist" that patients report.

Myths and facts about wrist pain

Myth vs. Fact

MYTH

Postpartum wrist pain is normal and will pass on its own

FACT

Postpartum wrist pain is not inevitable and should not be normalized. Without treatment, De Quervain's tenosynovitis can become chronic and seriously compromise care of the baby. Early treatment — including medical acupuncture, selective immobilization, and ergonomics — accelerates recovery and prevents chronification.

MYTH

I need to stop using my hand completely to improve

FACT

Complete and prolonged immobilization can weaken the tendons and muscles, worsening the prognosis. The correct approach is ergonomic modification: use the forearm instead of the wrist to support the baby, alternate hands, use a night splint for rest. Medical acupuncture allows pain relief without excessive immobilization.

MYTH

If the Finkelstein test is positive, the only option is injection or surgery

FACT

Corticosteroid injection and surgery are options for refractory cases. Many patients with De Quervain respond to conservative treatment that includes periosteal medical acupuncture along the first dorsal compartment, dry needling of the thumb extensors, and ergonomic guidance. These approaches are considered low-risk in the postpartum and during breastfeeding when performed by a qualified physician, with the usual precautions of acupuncture (antisepsis, controlled depth, monitoring of adverse events such as local pain, hematoma, or syncope).

Treatment protocol

Assessment and ergonomic guidance
1st visit

Finkelstein test and palpation of the tendons of the first compartment. Myofascial exam of the extensor pollicis brevis, abductor pollicis longus, and brachioradialis. Immediate ergonomic guidance: how to hold the baby, breastfeeding position, use of night splint if indicated.

Periosteal acupuncture and dry needling
Sessions 1-3

Periosteal needling along the radial styloid process — over the inflamed first dorsal compartment. Dry needling of the thumb extensors and brachioradialis. Electroacupuncture 2 Hz for local anti-inflammatory effect and analgesia.

Forearm musculature and stabilization
Sessions 4-6

Treatment of the radial wrist extensors and supinator when they contribute. Light isometric exercises for the thumb in neutral position. Progression to light eccentric exercises for the extensors as the pain decreases.

Maintenance and prevention of recurrence
Sessions 7-8

Spacing of sessions. Reinforcement of ergonomic guidance as the baby grows and gets heavier. Self-stretching of the thumb extensors. Assessment of need for splint for high-risk activities (carrying weight, prolonged phone use).

Frequently Asked Questions

Yes, with medical indication and follow-up. Medical acupuncture is considered low-risk during breastfeeding because it does not involve medications that pass into breast milk — dry needling and electroacupuncture are local mechanical procedures. As in any patient, adverse events of acupuncture (local pain, hematoma, vasovagal syncope and, more rarely, infection or pneumothorax depending on the área treated) should be considered. This route is usually a useful alternative in the treatment of De Quervain in the postpartum.

The splint for De Quervain (which immobilizes the thumb and wrist in a neutral position) is most useful at night and during high-risk activities. Continuous use is not recommended because it weakens the musculature. The medical acupuncturist guides selective use according to the severity of the picture and the patient’s daily activities.

It is possible, especially if the ergonomic guidance is not maintained. As the baby grows, the overload on the thumb tendons increases. The key is to adapt the way of carrying — using the forearm, not the hand — and to maintain preventive exercises. Sporadic maintenance sessions may be necessary in periods of greater demand.

Surgery for De Quervain (release of the first dorsal compartment) is reserved for cases that have not responded to conservative treatment for at least 3-6 months. Even in cases considered severe, a course of medical acupuncture is worth attempting before surgery, as it treats the myofascial component that may be amplifying the pain. If surgery becomes necessary, prior dry needling helps to optimize postoperative recovery.
