I went to the hospital today, but couldn't get my injections. Even though my hemoglobin is low, I cannot receive the injections because my iron is way too low. So now I have to make a call to my CF doc to see what he wants to do. I have to take a supplement, which I have been doing, but they want me to increase the amount to see if I can bring up my iron without infusions. So now I will have to wait a few weeks to get my blood checked again. Now we know why I am feeling so weak, besides low hemoglobin, I am very anemic. Will update when there is more news.
