@shoch1957 I experienced the same thing, especially when HG was in the 9s and dropping. I did not appreciate being told it was something else. I had fatigue early on. It was one of my first symptoms. I was told I should not feel that either. Eventually, I had my heart checked and a pulmonary function test. The anemia caused the racing heart. Since I was symptomatic, my transfusion point was set at 8 instead of 7.
