question: Hi,  I had a blood transfusion of two units two weeks ago after sudden blood loss from a bleeding ulcer.  When I left the hospital, by blood count was 10.  I had blood drawn a week ago and was up to 11.4.  But I am feeling so weak, dizzy and lightheaded--I am actually having a hard time driving, and have to lie down for frequent naps throughout the day.  If my blood was up to 11.4 a week ago, shouldn't I be over all of the dizziness, etc?
