all of a sudden, my right foot and ankle began to swell??? I m 74, in really good shape after dealing with 2o years ago small lacunar strokes, a stent inserted later, a HUGE LIFESTYLE change ( exercise and heart diet daily). I elevated my foot above my heart and the swelling has gone. I have the beginnngs of neuropathy in both feet (51 /2 years). i do not use salt! Why would I ALL OF A SUDDEN, have this swelling in my right foot?
