I am a 42 yr old cardiacpatient. In the last 3-4 days various body parts have been swelling up. At first, it was my left foot that was swollen on thesole of my foot. It affected the ball of my left foot and 3 toes. (big toe,and the next 2 toes) It was hard for me to walk for about 10 hours. Then, i went to sleep and woke up to no swelling at all. Later that day, myleft hand and the left part of my top lip swole up. I was talking and I noticed that my lip was feeling crazy. I looked in the mirror and it was swollen. I also noticed that there was a knot on my left hand that was swollen (the palm side) and my pointing finger and middle finger swole up as well!!! That lasted all day and night. I woke up and it had subsided.Then today, I was sitting an watching tv and I noticed my top lip was feeling weird. I went to look at it and noticed my top lip was swollen towards the middle part of my lip. It is still swollen as we speak Does anyone know anything about my dilemma? it is scaring me quite a bit because I am a cardiac patient and I have never had this isue before and it is getting weirder by the minute!! I haven't ate anything out of the ordinary.  Thanks for any advice you give
