I have high blood pressure and am on meds for it and have a monitor to check it daily. Is your blood pressure up? Do you have a headache that doesn't go away? Is your face and hands swelling too? If not, I wouldn't worry about it, but give your doc a call for piece of mind. Be advised though, they may give you the standard "go to the er" advice. Last time I took that advice and went I ended up having to pay $150 there and got billed for $350 in additional doc's fees, all for nothing. I have swelling in my ankles and feet to, usually after being on them too much. I sleep with my feet elevated at night and by morning they look better, although not completely un-swollen looking. I called my doc in a slight panic when I noticed they were swollen particularly bad, almost round all the way around, left a message and didn't get the message they gave me to go to the er. By the time I checked the message the swelling had gone down and everything was fine. I talked to my doc last visit and she said it is normal and the problem may be not getting enough water. Drink more water and elevate your feet. I've had preclempsia before, and if you have headaches that won't go away for a few days, and swelling in the face or hands that is when you go to er. Don't worry.
