I am suffering from terrible shortness of breath. I have taken my loading injections of B12 (the first one I took a month ago now) and still very bad breathlessness.
I have read that shortness of breath is caused by low red blood cells as they help carry oxygen in the blood. However when my red blood cells appear in the normal range on my blood test results then how can this be what's causing it?
Thank you for your help anyone. Much appreciated
