loves................it could be related to your blood pressure............
just walk in any fire dept and they will take it for you!!!! ( they will here anyhow)Thats a plus........find out how your pressure is and see the hotties!!
or as someone else said..........go to the grocery store or pharmacy...........
edema can be related to some more serious issues, which I'll bet is why noah is on you about it..............
try the things others here have told you....no salt etc and check the pressure.......
and if all elase fails go to an ER they have to treat you ins or not
