question: My mother in law has been in ICU 8 times since August 2009-she keeps having to get blood transfusions because it disappears-but does not come out of the body. But everytime she gets blood-she ends up with high heart rate, high blood pressure, can not breathe, plus she has also had swelling in feet and hands when this happens and trembles just all of the sudden. We live in southwest virginia and no doctors can find anything to pinpoint these things to. On Tues morning she had two units of blood and by midnight she was rushed to ER, not able to breathe, ended up on a ventalitor(SPELLING) and today she is somewhat better but has been on oxygen at home since Nov. We need help and we do not know where to go with this. Is there a chance that she might have contacted Human Parvovirus. Help
