Hi, Treatment may depend upon the cause. common causes are like peripheral vascular disease or deep venous thrombosis or cellulitis or eczema etc. Swelling may be due to cardiac failure or renal failure or liver failure etc. Until examination is done it is difficult to say what it is. Elevate the limbs, use crepe bandage. If symptoms not improved please consult your doctor he will examine and treat you accordingly. Hope I have answered your query. Let me know if I can assist you further.
