I am a 60 year old man and I have chronic swelling, but no real pain, in my left ankle and foot. I am in good health and on my feet alot, but I have never had persistant swelling, without being injured. I was a runner for many years, but don t anymore. However I do walk about 3 miles a day. I went to my Family Doctor had an ultrasound run, which came back negitive. He was checking for deep vein thrombosis. I am taking anti inflammatories (2 Naproxen) morning and night and my blood pressure medicine has a diuretic in it, and I still have swelling. I have encountered bouts with swelling before but never this ofter nor this long. What is happening?
