I have Hemoglobin H Disease and my Hg level is at a constant high 7 and once in a blue moon, it hits 8.
I DID do a short transfusion therapy regime 2 years ago to see if it would help alleviate my symptoms, but my Hg count went to 9.6 and I didn't seem to notice much, if any, difference from the one-time transfusion and so my hematologist said that I might need constant transfusion therapy for me to notice a difference.
I know I'm at pretty low numbers, but I'm used to it (though admittedly struggling as well) and I'm also scared of starting transfusion therapy on a more permanent basis.
