Also, regarding the swallowing problems, evaluation with an upper GI or upper endoscopy can be considered to exclude a mass or stricture that may be impeding the proper swallowing mechanism.
This also can be discussed with your personal physician.

Apologies for the delayed response, I was on vacation.
There are a variety of reasons for leg and feet swelling, including, heart and kidney disease. It appears that you have had a variety of tests that have evaluated for these conditions, but if it hasn't been done already, an echocardiogram and blood tests looking at the kidney function should be done.
An ultrasound of the legs can also be considered to exclude a blood clot.
Otherwise, if the tests remain negative, compression stockings can be considered to help reduce the swelling.
These options should be discussed with your personal physician.
