Thanks, Mrs.D. I've read that. Mine is likely autoimmune, though perhaps cancer is possible. I definitely don't have an acute viral infection. But there are many potential infections that could cause it. I definitely don't have folate deficiency, but I haven't checked my copper. No way of knowing until I have a bone marrow biopsy I suppose.

Pinkey, thank you too. I'll definitely update. But it may take a few months to get to the bottom of this, if not longer. I'll push to expedite the process.
