Tingling, numbness, burning, or pain in the hands can be frustrating at any time—but during pregnancy or after having a baby, it can feel overwhelming. These symptoms are often caused by carpal tunnel syndrome (CTS), a common condition that affects many pregnant and postpartum women.
Carpal tunnel syndrome happens when the median nerve, which runs through a narrow space in the wrist called the carpal tunnel, becomes compressed. During pregnancy, changes in hormones and fluid levels make this nerve more likely to be irritated. The good news is that most people improve with conservative physical therapy treatments, and surgery is rarely needed.
Carpal tunnel syndrome affects a large number of pregnant people. Studies estimate that about one in four to one in three pregnant women experience symptoms. It most often begins during the third trimester, when fluid retention and hormonal shifts are at their peak.
Pregnancy hormones cause tissues to soften and swell. At the same time, the body holds on to more fluid. This extra fluid increases pressure inside the carpal tunnel, leaving less room for the median nerve. As a result, nerve signals do not travel as smoothly, leading to numbness, tingling, weakness, or pain—often worse at night.
Pregnancy-related carpal tunnel tends to be more severe than carpal tunnel seen in the general population. It is more likely to affect both hands and may cause symptoms throughout the day instead of only at night. Risk factors include older maternal age, gestational diabetes, higher levels of swelling, and symptoms that start early in pregnancy.
Many people are told that carpal tunnel will go away once the baby is born. While symptoms often improve after delivery, this is not always immediate.
Research shows that more than half of people still have symptoms one year after giving birth, and about one-third continue to have symptoms three years later. Symptoms are more likely to last if they began early in pregnancy, were severe, or if postpartum depression is present.
Because symptoms can linger, early treatment during pregnancy and postpartum is important—not just to reduce discomfort, but to protect long-term nerve health.
The most effective and safest treatment for pregnancy-related carpal tunnel syndrome is nighttime wrist splinting in a neutral position.
A neutral wrist position means the wrist is kept straight—not bent forward or backward. When the wrist bends during sleep, pressure inside the carpal tunnel increases. A splint gently holds the wrist in a neutral position, giving the median nerve more space and allowing it to calm down overnight.
Studies show that wearing a neutral wrist splint at night for four weeks significantly improves symptoms compared to no treatment. Neutral splints are also more effective than splints that hold the wrist in extension, especially for nighttime symptom relief.
This approach is completely safe during pregnancy and directly addresses the swelling and hormonal changes that cause nerve compression. For many people, nighttime splinting alone provides meaningful relief.
While splinting is the foundation of treatment, nerve and tendon gliding exercises can further improve outcomes when used alongside splints.
Tendon gliding exercises help the finger flexor tendons move smoothly through the carpal tunnel. These exercises involve moving the hand through five positions: a straight hand, a hook fist, a full fist, a tabletop position, and a straight fist. These gentle movements reduce stiffness and improve tendon mobility.
Nerve gliding exercises focus on helping the median nerve slide and stretch without irritation. These movements typically involve opening and closing the hand, extending the fingers and wrist, gently moving the thumb, and rotating the forearm. When done correctly, nerve glides should feel gentle—not painful or aggressive.
Research shows that people who combine splinting, activity modification, and nerve gliding exercises are more likely to have normal nerve testing results after three months compared to those who use splinting alone.
Hands-on care provided by a trained therapist can also be very effective. Manual therapy has shown the highest effectiveness for short- and medium-term pain relief in recent research reviews.
Manual therapy may include soft tissue massage, gentle joint mobilization, and specialized nerve mobilization techniques. These treatments help reduce tissue tension, improve circulation, and calm irritated nerves. Manual therapy is typically used as a complement to splinting and exercise rather than a stand-alone treatment.
Carpal tunnel syndrome is extremely common during pregnancy and after birth. It is caused by normal hormonal and fluid changes, not by anything you did wrong.
Wrist-neutral nighttime splinting is the most effective and recommended first-line physical therapy treatment, and it is safe during pregnancy and postpartum. When combined with nerve and tendon gliding exercises and, when appropriate, manual therapy, many people experience meaningful relief.
If symptoms are severe, long-lasting, or worsening, additional medical options such as injections or surgery may be considered—but for most people, conservative physical therapy works well.
Early treatment can reduce pain, protect nerve health, and make daily tasks—like sleeping, caring for a baby, and returning to work—much more comfortable.
