sorry to hear you're going through this. it sounds like you've done the right thing by seeing your doctor and having your heart and kidneys checked out. i'm not sure why you're taking aspirin unless your doctor specifically recommended you take it. aspirin will not address the swelling issue you describe. aspirin will treat swelling due to inflammation (such as from an injury) to some extent but it will not have any effect on swelling due to edema (water retention) which is what you seem to be describing. i suggest you discontinue the aspirin unless otherwise directed by your doctor. it is not uncommon for people to retain fluid in the legs as they age. even very active people can have issues with fluid retention in the legs simply because the veins don't work as well when we age. i suggest you return to your doctor to discuss the issue in more detail. it's possible as you say he does not have an answer for the swelling problem. but it's also possible the issue simply requires more investigation to arrive at a diagnosis. if you're concerned about the swelling and frequent urination (i would be! ) then that's a good enough reason to return to your doctor for more conversation. wishing you well!
