De Quervain's Tenosynovitis: Postpartum Wrist Pain
The short answer
De Quervain's tenosynovitis, often called "mommy thumb" or "mommy wrist," is inflammation of the tendons on the thumb side of the wrist. It is very common in new parents due to the repetitive hand positions used when lifting, holding, and breastfeeding a baby, combined with hormonal changes and fluid retention that affect the tendons. Treatment includes thumb splinting, modifying how you lift your baby, anti-inflammatory medication, and in persistent cases, a corticosteroid injection that is highly effective.
This is one of the most common questions parents ask. Searching for answers means you care.
By Age
What to expect by age
0-6 weeks postpartum
Wrist and thumb pain often develops in the early weeks as new parents repeatedly lift, hold, and position their baby. The pain is typically on the thumb side of the wrist and worsens with gripping, twisting, or making a fist around the thumb. Postpartum fluid retention and hormonal changes can contribute by causing swelling around the tendon sheath. Early treatment is important: wear a thumb spica splint (available at pharmacies), apply ice for 10-15 minutes several times daily, and modify how you pick up your baby by scooping rather than using an L-shaped hand position.
6 weeks to 3 months postpartum
If symptoms persist despite conservative measures, see your provider. Ibuprofen can help with pain and inflammation and is safe while breastfeeding. A corticosteroid injection into the tendon sheath is the most effective treatment, providing relief in approximately 80-90% of cases, often with a single injection. The injection is generally safe during breastfeeding. Continue wearing a splint, especially at night, and be mindful of hand positioning during baby care. Physical or occupational therapy can teach you ergonomic techniques for lifting and holding.
3-6 months postpartum
As your baby gets heavier, the strain on your wrists increases. If you have not sought treatment, do not delay further. Chronic tendon inflammation is harder to resolve than acute inflammation. Exercises to strengthen and stretch the thumb and wrist tendons can be helpful once the acute inflammation has subsided. Your therapist can guide appropriate exercises. Adjusting breastfeeding positions to reduce wrist strain (using pillows to support the baby's weight) can also help.
6+ months postpartum
Most cases of de Quervain's resolve with proper treatment within a few months. If symptoms persist despite splinting, anti-inflammatory medications, and steroid injections, surgical release of the tendon sheath is an option with a high success rate. The procedure is typically outpatient with a relatively quick recovery. Once resolved, the condition does not usually recur unless there is another pregnancy or similar repetitive strain. Maintaining good wrist ergonomics during daily activities helps prevent recurrence.
What Should You Do?
When to take action
- Mild wrist or thumb soreness after long periods of holding your baby that resolves with rest
- Temporary discomfort that improves with splinting and modified lifting techniques
- Gradual improvement over weeks with conservative treatment
- Wrist or thumb pain is persistent and interferes with your ability to care for your baby
- You hear or feel snapping or catching when you move your thumb
- Pain is not improving after two weeks of rest, splinting, and anti-inflammatory medication
- You notice weakness in your grip or difficulty holding objects
- You experience sudden severe wrist pain with swelling, redness, and warmth, which could indicate infection rather than tendonitis
- You lose sensation in your thumb or fingers, suggesting possible nerve involvement

Exercise After Birth: When to Start Safely
Most people can begin gentle movement like walking and pelvic floor exercises within days of an uncomplicated vaginal delivery. After a cesarean delivery, recovery typically takes longer and you should wait for provider clearance before anything beyond gentle walking. ACOG recommends that postpartum individuals can gradually resume exercise when they feel ready, rather than waiting for a specific milestone, though a postpartum checkup is important to assess readiness for higher-intensity activity.
Episiotomy Healing: Tips and Timeline
An episiotomy typically takes two to four weeks to heal, though deeper cuts may take longer. Pain and discomfort are most intense in the first few days and gradually improve. Key strategies for healing include keeping the area clean, using sitz baths, applying cold packs, and taking recommended pain relievers. Most stitches dissolve on their own within two to four weeks.
Returning to Running After Baby
Current guidelines recommend waiting at least twelve weeks postpartum before returning to running, and only after being cleared by your provider and ideally assessed by a pelvic floor physical therapist. Running is a high-impact activity that places significant demands on the pelvic floor, core, and joints, all of which need time to recover after pregnancy and birth. Returning too early can lead to pelvic floor dysfunction, urinary incontinence, and injury.
Dealing with Abnormal Prenatal Screening Results
An abnormal prenatal screening result can be terrifying, but it is important to understand that screening tests are designed to cast a wide net and have significant false-positive rates. Most people with abnormal screening results go on to have healthy babies after further testing confirms the baby is fine. An abnormal screening is a reason for more information, not a diagnosis.
Pregnancy Over 35 (Advanced Maternal Age)
While pregnancy after 35 carries some increased risks (including chromosomal abnormalities, gestational diabetes, and hypertension), the vast majority of people over 35 have healthy pregnancies and healthy babies. The term "geriatric pregnancy" is outdated and does not reflect reality. With appropriate prenatal care and monitoring, outcomes are excellent.
Amniocentesis Questions and Fears
Amniocentesis is a diagnostic test performed between 15-20 weeks that analyzes amniotic fluid to detect chromosomal conditions and genetic disorders with over 99% accuracy. The risk of pregnancy loss from the procedure is approximately 1 in 500-1,000 when performed by an experienced provider. Understanding the actual risks can help you make an informed decision.
