My ankles & feet have been swollen for a couple weeks (right foot more than left). I do take a daily water pill, but doesn t seem to help with swelling. I have some redness(pale( in the right shin from foot to half way up to knee. It is somewhat tender in that area. I do have a porcine aortic valve & have been on Metroprolol, Furosemide, Digoxin & Warfarin for A-Fib. Concerned about swelling, tightness & redness of right foot, ankle & leg. Are these signs you have before a heart attack?
