my husband s doctor just called him to his office and told him his hemoglobin level is 5.5,,,and told him it is probably due to a bleed somewhere,,,and wants him to get a transfusion tomorrow. I feel this should be addressed immediately,,,what is your opinion?,,,,,he is cold,,,looks pale,,,and is very tired all the time,,,,I have been telling him to talk to his doctor about this,,,he had his regular physical and blood work earlier this week,,and they called him to the office today and this is what they told him.
