Hi, Welcome to health care magic, Swelling over leg,ankle or foot could be of variety of causes like cellulitis or deep vein thrombosis or Some kidney diseases or peripheral vascular disease or varicose veins but doctor can not say any particular diagnosis without complete history taking and thoroughly clinical examination. I think you should consult nearby doctor preferably general surgeon for further evaluation. You may need some diagnostic tests such as - complete hemogram, kidney function tests, blood electrolyte levels, ECG and stress ECHO, venous Doppler of the legs and urine tests to help us identify the cause. Meanwhile, you can take analgesics and serratiopeptidase to reduce edema and pain but only after doctor s prescription. Keep your limb above the grounds and avoid any weight bearing or physical exertion. Thanks and regards,
