Hi, newbie non-professional with a question: I have received stored blood transfusions following postpartum or miscarriage hemmorhage 3 times (in 11 years). I have been diagnosed with impaired adrenal function, which is undoubtedly the main cause of my often overwhelming fatigue, but I have a recurring symptom which seems to indicate my cells aren't receiving enough oxygen. I often get that "lactic acid" burn feeling when simply walking around thehouse, going up a few stairs, etc. in my muscles, as well as shortness of breath. I'm curious as to how stored blood functions in the body long term, and what if anything, I can do to improve my blood oxygenation. I'm responsible for a large family and need all my energy! Thanks!
