What to do with swollen legs

Swollen legs are sometimes caused by standing for a long time or sometimes, hours of running errands. When we do these things, there is a fluid build up in our legs called edema. The gravity prevents the fluid from getting pumped to the kidneys giving our legs a thick appearance. I found out from one article a simple way to relieve this. Simply lie on the floor and elevate your legs by resting them on a chair. Rotate your ankles for 2 minutes then massage your calves in the direction of your heart for 2 minutes. According to research, this simple and easy trick can ease fluid build up within 30 minutes. I have tried it and it worked!
