Edema is swelling caused by excess fluid trapped in your body's tissues. Although edema can affect any part of your body, it's most commonly noticed in your hands, arms, feet, ankles and legs.

Mild edema usually goes away on its own, particularly if you help things along by raising the affected limb higher than your heart.
