I thought I had been getting along fairly well with my treatment regime of weekly methylcobalamin injections. I had cut back on folic acid tablets to only once a week and hadn't had a return of mouth ulcers, so I figured that was fine also. In Feb I had a noticeable uptick in my level of fatigue which was followed by a weak/shaky feeling if I stood for more than a couple of minutes. It was discovered that I'm hypoxic.
I've had a bunch of tests done which have ruled out heart problems and seem to have ruled out lung problems as well. That leaves blood as the only other possible troublemaker. Weirdly, my blood test results have all been good. I'm not showing any signs of anemia with one exception; a blood smear was done and it showed hypochromia. I had iron studies done a month ago, and I wasn't low in iron then. I suppose that might have changed in a month, but it seems unlikely.
I know this forum is for PA, and I think my PA is still well treated and that this hypoxia problem is related to something else. The trouble I'm having is that I suck at research and, when I try to look up hypochromia, all I find are references to iron deficiency anemia and results that are microcytic/hypochromic. My results were really normocytic/hypochromic. I'm trying to figure out if a result of "hypochromic 1+" would be severe enough to account for my blood oxygen level dropping to 83% on exertion. Can someone tell me how to go about looking this up?
