I have a support group member who had a CAR-T about 9 months ago. His myeloma numbers are 0. But over the past month or more, he is "losing" blood, or probably not making enough blood. He is anemic, Hemoglobin down to 7 and 8. Very tired, not much appetite. He has had a blood transfusion, but his drs are not sure what is going on. Has anyone had something similar? Any thoughts?
