Thumb-side wrist pain during pregnancy

By trimester

Weeks 1–13

1st trimester

Thumb and wrist tendon pain from De Quervain's is uncommon this early, since it's driven mainly by fluid retention and repetitive grip that build up later in pregnancy and after birth.

Weeks 14–27

2nd trimester

Some people start noticing early thumb-side wrist discomfort in the second trimester as relaxin loosens connective tissue throughout the body, though it's still more typical for this to begin in the third trimester.

Weeks 28–birth

3rd trimester

This is when De Quervain's most often begins, as fluid retention peaks and swelling narrows the tunnel the thumb tendons glide through. A removable splint is a reasonable first step to ask your provider about.

What does the evidence show for thumb and wrist pain?

• De Quervain's tenosynovitis is the second most common hand and wrist problem in pregnancy, typically developing in the third trimester as fluid retention and repeatedly picking up the baby cause swelling of the tendons at the base of the thumb. 1
• The thumb-side tendons become squeezed inside a narrow tunnel at the wrist as the tissue around them thickens, which is different from carpal tunnel syndrome, where numbness and tingling follow the median nerve into the fingers rather than pain concentrated at the thumb side of the wrist. 2
• In a study comparing 63 postpartum women with De Quervain's to 630 without it, a pregnancy lasting more than 40 weeks, a first childbirth, and a higher pre-pregnancy BMI were all linked to higher odds of developing the condition, with symptoms typically starting around 5 months after delivery. 3
• Splinting, anti-inflammatory medication, and a corticosteroid injection into the tendon sheath are the standard non-surgical options, and research on steroid injections specifically states they can be used safely during pregnancy and breastfeeding provided there's no other reason to avoid them, a decision your provider should make with you. 1
• Corticosteroid injections for De Quervain's have shown sustained relief in the large majority of patients at six-month follow-up in general, non-pregnancy-specific studies, and the condition overall tends to be self-limiting, often resolving on its own once frequent lifting or breastfeeding eases up. 4

When should I call my provider about thumb and wrist pain?

Pain that's centered at the thumb side of the wrist and worsens with gripping or pinching is the typical pattern of De Quervain's, which isn't dangerous on its own. Numbness, tingling, or weakness that spreads into your fingers points toward carpal tunnel syndrome instead, a different condition that's also common in pregnancy and worth mentioning separately to your provider. If pain, swelling, redness, or warmth comes on suddenly, is severe, or is accompanied by fever, that pattern doesn't fit ordinary tendon swelling and deserves a prompt call to rule out another cause. If you are ever unsure which side of the line you are on, make the call. Obstetric teams handle these check-ins as routine, not as overreacting.
