Edema in ankles/lower legs

Hi, could anyone please advise the quickest remedy for reliving or removing edema or fluid retention in the ankles and lower legs (as of now, do we not know the cause, if it is due to any organ weakness or function)

We have tried garlic with water which did not work, i have read about cayenne pepper, watermelon, serrapeptase, etc; I have also read about taking Sea Salt with water but think it contridicts the low sodium advice; so I am lost and not sure what to do...

Are there OTC medication we can get some releive first...

All advice and help highly appreciated. Thanks Tweet
