Hi! I found out about half a yr ago that I had extremely low hemoglobin, probably pernicious anemia; it made running xc a painful ordeal. I kno I most likely had it for a good yr before. around this time was when my legs, my thighs esp would start swelling up for no reason at all. I get out of bed in the morn, start brushing & they'll start swelling. Can this be linked somehow to anemia? which is better now. I also had a doctor tell me that there was something off with my kidneys. Could it be related to that then? Thanks for your time!
