I have iron deficiency anemia, so far in spite of all the tests there is no known cause. I m taking 2 over the counter Iron tablets w/meals daily, and have had an iron infusion, so far no good results. In the mean time the doctors have me off of anti-inflammatory drugs, so with my arthritis I am in lots of pain. Also I was recently discovered to have A-fib, so I m now on Xarelto, when I think it s all very confusing to me..
