Unfortunately I had the same problem through out my entire pregnancy. Like your doctor said stay off your feet as much as you can, but if you have to work, then make sure when ever you're not working, stay off of them. When you go to bed at night, put 2 pillows under them, and sleep with them propped up. The elevation will help reduce the swelling. Also, if you haven't already, make sure they check your blood pressure to make sure it's not caused by that. I Hope the swelling goes down soon, I know it's extemely uncomfortable, but it will all be worth it in the end! :o) Congratulations!!!
