Edema of the legs and feet requires emergency care if it is accompanied by shortness of breath or chest pain, according to MedlinePlus. Patients who have experienced heart disease, kidney disease or liver disease should contact their doctors immediately if their lower extremities suffer swelling that is persistent or worsens.
Symptoms of edema in individuals who do not need immediate medical care can be treated with home remedies, states MedlinePlus. These include keeping the legs elevated while lying down, exercising the legs, reducing salt intake, losing weight, wearing support stockings and not wearing tight clothing. Common causes of edema are being overweight, aging, leg infection, blood clots and poor or weak circulation.
