Carpal tunnel syndrome in pregnancy

Carpal tunnel syndrome is a common condition in pregnancy, affecting up to half of pregnant women. Symptoms include:

• numbness in the hands
• tingling and pain in the thumb and fingers of one or both hands
• occasionally, reduced manual dexterity.

Symptoms are usually worse at night. 

Causes and treatment

In carpal tunnel syndrome one of the main nerves becomes compressed as it passes from the forearm into the hand through the 'carpal tunnel' at the wrist. During pregnancy hormonal changes lead to fluid retention. This can narrow the carpal tunnel and put pressure on the nerves, causing the pain or numbness in the fingers.

Treatment is usually aimed at relieving the symptoms. Painkillers such as paracetamol may help during pregnancy, while anti-inflammatory drugs can be used after your baby is born if the symptoms persist. A wrist splint used at night can also help to alleviate symptoms. 

If you are suffering from any of the symptoms listed above, speak to your doctor or midwife who may refer you to a physiotherapist.

Carpal tunnel syndrome after birth

Most cases of carpal tunnel syndrome resolve within six to twelve weeks after birth. If you still have symptoms after this time, seek medical help as you may need treatment to avoid permanent damage.
