Why Do My Feet Swell up?


Foot swelling is characterised by a build-up of fluid in your foot. Swelling of the foot may be caused by being overweight, blood clot in the leg, increased age, leg infection and inability of veins in the legs to properly pump blood back to the heart. Injury or surgery involving the leg or foot can cause swelling.
