Swelling

Swelling in my calves has started the past couple days. It makes it hard to do anything! I get sharp pains in my legs any time I am on my feet too long. It is so uncomfortable! I am so nervous about spider and vericose veins also. They run in my family so I’m sure it’s gonna happen eventually but i would rather them happen much later than sooner..I know it doesn’t help that I am heavier now so I have been trying to keep my weight gain under control this pregnancy since I still haven’t lost all the weight from my first. Anyone have any tips to help with the swelling? Other than staying off my feet and propping them. I do as much as I can of course but realistically nothing would ever get done if I sat down all the time! I crave ice water so bad all the time too so my water intake should be okay. Thanks ladies!
