What wrist and hand pain is and why it happens in pregnancy
Nicola Tik
Wrist and hand pain is more common during pregnancy than many people expect. It can feel like stiffness, aching, tingling, or a sense of weakness in the hands, and it tends to become more noticeable as pregnancy progresses. Understanding what is driving it can make it feel less confusing and help you manage it more effectively.
Two things combine to make the wrists and hands more vulnerable during pregnancy. The first is fluid retention. As your body produces significantly more blood and fluid to support your growing baby, some of that fluid accumulates in the tissues of the hands and wrists. This increases pressure in an already compact area, particularly around the structures that run through the wrist.
The second is the effect of relaxin, the hormone that loosens ligaments across the body during pregnancy. While its primary job is to prepare the pelvis for birth, it affects connective tissue throughout the body, including around the wrist and hand joints. This can contribute to a sense of looseness or instability, particularly during activities that place load through the hands.
The most common wrist and hand condition during pregnancy is carpal tunnel syndrome. The carpal tunnel is a narrow passageway in the wrist through which tendons and the median nerve pass. When fluid retention increases pressure in this space, the nerve can become compressed, leading to tingling, numbness, or aching in the thumb, index, and middle fingers. Some people also notice a weaker grip or find it harder to do tasks that require fine movement.
Carpal tunnel symptoms during pregnancy are most common from the second trimester onwards, when fluid retention tends to be at its most significant. Many people find symptoms are worse at night or first thing in the morning, when fluid has had a chance to accumulate during rest.
The way you use your hands and arms day to day also contributes to how your wrists feel during pregnancy. Sustained positions that keep the wrist bent, whether at a keyboard, holding a phone, or carrying bags, can increase pressure through the carpal tunnel and surrounding structures. As pregnancy progresses and postural changes affect the shoulders and upper back, the load through the entire arm from shoulder to wrist can shift in ways that make the wrists and hands more sensitive.
In early pregnancy, wrist and hand symptoms are less common and tend to be milder when they do occur. By the third trimester, fluid retention and postural load are both at their greatest, and symptoms often feel most pronounced during this period.
For most people, wrist and hand symptoms ease significantly after birth as fluid levels normalise and hormonal changes settle. In the meantime, understanding what tends to aggravate symptoms and what helps is a useful starting point, which is what the next article in this series covers.
