What causes carpal tunnel in pregnancy?
Your belly isn't the only part of your body that swells during pregnancy, and fluid retention in the arms and wrists can put pressure on nerves there. The result: a temporary case of carpal tunnel syndrome. This condition shows up in about a quarter of all pregnant women, making hands and wrists feel numb and achy. If the numbness is limited to your fingertips, postural changes in your upper back- in response to your changing center of gravity- may be putting pressure on nerves near your shoulders.
