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?
