Your Pregnant Body
Hands, Wrists, and Arms
Side effects: Carpal tunnel syndrome, red palms
In the third trimester, because of fluid retention, the nerves snaking through tiny passageways are likely to be pinched by swollen tissue, which can lead to, or worsen, carpel tunnel. Occasionally, the shooting pain, numbness, and tingling can migrate to the forearm and shoulder.
As veins enlarge to accommodate greater blood volume, and capillaries branch out to handle the increase, the skin all over your body enjoys greater blood flow. Consequently, some women's palms (or soles of the feet) become reddened after about 12 weeks.
