Hi, Swelling limited to feet and ankles that occurs by evening and fades by elevation or next morning is dependent in nature, and usually occurs in those people who are subjected to prolonged periods of standing and is physiological in nature. In case it is persists and do not go away with rest then that should be considered as pathological. You need to get a kidney function test done along with a venous color Doppler study to rule out the two of the most common pathological causes. Take care. Hope I have answered your question. Let me know if I can assist you further.
