Help with swelling?? Anyone have ideas?

Caitlyn

Im 40wks 1d and for a week and a half my feet and ankles have swollen up like marshmallows. Now my feet dont bother me too much other than the tightness of the skin, but my ankles hurt and feel like theyre bruised.

I dont have a high salt intake and they can even swell when i havnt eaten for the day. Elevating my feet doesnt seem to help either. Any ideas what i can do to ease the swelling
