I don't have blood cancer, and sad to hear you do. They don't know what the root cause(s) of my 4-yr long saga is, but my new primary is sending me to an immunologist initially bc of abnormal bloodwork. As for the impact of Covid in general, I don't think the long-term impact has been felt fully as of yet. I think it will be a few years to grasp the depth and breadth of the global impact. I retired bc of it; not bc I was ready for retirement, but because I have Long Covid. It propelled the aging of my body tenfold. Went from being energetic, full-speed Corporate America mgmt level, with great career financially, to full-stop in every category.
