I have bilateral swelling in both feet and ankles, what is the cause of it ?

I have had this bilateral swelling for the last few months and no one can come up with an answer for it , Please someone what can I do to help the swelling and pain go away… They ruled out a lot of things includes Fou, water retention, liver, kidney, and hear… What else could it be

As you ruled out the things related to heart, kidney, liver and many others, it could be due to Venous insufficiency((leg veins with a problem returning blood to the heart) or some prescription medications. Also check out for arthritis.
