for about 1 month now my feet have really been becoming swollen by the end of the day. I sit at a computer and have has some history of some swelling but not to this extent. By morning the swelling has go down. Only my ankles and feet swell. The only different thing that I have started is drinkiing more water, 10-12 glasses a day and taking a new multi vitamin. What could be causing this extreme swelling. It really is starting to concern me. I am not pregnant and have had a tubal 12 years ago and even when I was pregnant, I never swelled to this extent. I also have a low salt intake and have started watching calories and exercising. I am 42 and weigh about 130 @ 5'4". Please give me some suggestions.
