I remember that swelling, i got it often, all i can say is feet up, feet up, feet up!! Its when you have been on them all day and had them dangling down too long (sitting on chairs) that it gets bad, so try laying down and/or putting them up. Also try changing your shoes to more loose fitting ones if you can, thongs/slip on sandal type things are best. That said though, you must be careful, if its come on suddenly, keep a close eye on it, definitely mention it to ur ob next visit and get checked earlier if you have any other symptoms like headaches, spots in front of eyes etc. as it can be the start of pre eclampsia.

With your hip, have you tried sleeping with a pillow between your knees? Also a brace might help. Dont put up with the pain, definitely get in to see the physio soon.

Hope you get some relief soon.
