Hi Melanie
Did you get anywhere with the above situation? A few years ago I had become anemic by suspected foot strike hemolysis. It was when my 10k time went down by 6 minutes that I decided to get a blood test and found out. I had an iron infusion and was a changed man very quickly.
But now I find myself in a situation where my feritin levels are ok but my red blood cell count is way below expected range. An infusion isn’t the answer this time and I don’t now what is.
