well all the swelling ended up being pericarditis, but no one seems to be able to tell me how it occurred. Anyway after a few days in there I am home and am not at the mercy of their horrid food. Yay. Can't take anti inflammatories so it is will a bit of a long journey to heal. At least I can breathe a lot easier and massive doses of lasix have cured that swelly feet thing. The skin on my feet sort of look like old parchment now, all wrinkly, but so much thinner.
