What does it mean if the top of my left foot is swollen and red? I do not remember hurting it or twisting my ankle, nor did I fall down. I gradually started feeling discomfort while doing daily tasks like laundry, etc., then increasing into pain before I finally sat down and used an ice pack. I have had 2 aortic valve replacements so far, 1993 and 2006. Might this pain be a warning? Please respond. Thank you for your time and patience. Namaste. katie 55yr old 5 2 , 158 lbs, bp 116/66 p 60.
