Your body grows and changes at a dramatic rate during pregnancy, which can put additional stress on all the places where your body bends, including elbows, knees, fingers and hips. Especially if this is your first baby, your body is getting used to the redistribution of your weight, which can cause occasional discomfort.
What is the reason of this?
Weight gain is the main cause of joint pain because your bones have more to support. Your baby is growing, your center of gravity is changing, and your abdominal muscles are overstretching. In addition, the hormones released during pregnancy loosen up your joints, making their job a little more strenuous. If joint pain is particularly bothersome in your fingers and wrists, it could be a sign of carpal tunnel syndrome, which is common in pregnancy due to fluid buildup in your hands and fingers. Regular exercise is important when you're pregnant, but if you push yourself too hard, you may be putting stress on your bones and joints.
Tips
Mild joint pain is not an alarm, as general pain and stiffness are to be expected during pregnancy. Be sure to stretch, rest, and lift your feet as much as possible before reaching for Tylenol or other medications. If you think your joint pain is the result of a previous injury, you may want to talk to your healthcare provider to have it checked out.
