Has anyone been told that they have large red blood cells. I have been repeated told this over several years by several doctors, and they have advised me to take B12 injections. In reseaching this I found an interesting topic on Haemochromatosis, which is iron overload in the body. Has anyone been diagnosed with Haemochromatosis, and what can be done. Large red blood cells, arthritis, CFS, joint pain etc. are symptoms, and I have them all.... Thanks for any info.
