Oh, that sucks, I hope you've been able to correct it. I've just been through a battery of tests since Jan. when I finally got a new doctor who was willing to look into it instead of telling me to "eat right and exercise." Blood tests show my iron is fine but my B12 is low and I have systemic inflammation. We've ruled out everything else and my symptoms started a week after I had Covid so she's now confident that she can send me to a specialist for long Covid.
