What Are the Causes of Swelling in Feet & Legs?
Fluid accumulation and swelling of the lower extremities–including the feet, ankles and legs–is called peripheral edema, according to MedlinePlus. The swelling may be uncomfortable but generally is not painful. It’s most commonly seen in elderly people. There are many different causes of lower extremity edema, but a few specific causes constitute most cases–including venous insufficiency, orthostatic edema, certain medications, pregnancy, and lower extremity fluid accumulation from heart, kidney or liver failure.
