The increased blood volume of pregnancy will be redistributed in a few weeks post delivery. Your ankles and feet thus may get swollen. While there is little you can do except wait for the swelling of your feet to decrease there are some remedies you can try to alleviate some of the discomfort.
Elevate your feet
Resting your feet up on a stool or box when you sit down will help excess fluid drain from your feet and ankles.
Don’t cross your legs
Sitting with your legs crossed can make any fluid retention worse so try and remember to sit with your feet flat on the floor.
Stretch your legs
If you sit at a desk all day make sure you take regular breaks to walk around and stretch your legs, again giving your circulation a boost.
If it is your calves/legs are painful however, do go see a doctor, as it could be deep vein thrombosis.
