Swelling?

Babyy • Going through this daily pregnancy journey...
I'm 34 weeks pregnant... My ankles, feet, legs have been swelling a lot lately. It is really painful and uncomfortable at times. I have reduced salt intake, I drink almost 2 or more liters of water a day and I elevate my feet/legs often. What can I do to alleviate/reduce the swelling??! Also, is it normal for my arms, hands and sometimes face to swell along with my feet? I've had this happen a few times, told my doctor but she really didn't say anything. TIA.
