Been gone to the ICU

I've been gone to the ICU the past few days - took dad to his doctor to have something done about cramping in his legs and swelling in his ankle that would not go away (the stuff they x-rayed his ankle for three weeks ago) and his doctor (who just got back from a month long vacation) slammed him into the ICU where they put 6 units of blood into him and held him for three days as they treated him for unknown cause of blood loss and for congestive heart failure - the symptoms of which was what we been telling her stand in and two heart specialists he's had for a month now =-o
