I don't know the answer either but I would think it would take a little bit of time for the immune system to recover.
Not sure. I know someone who was treated by an LLMD, pronounced cured, and STILL has a low CD57. The LLMD said maybe it's just normal for that person.
In the old days, who ever checked CD57 anyway?? Maybe some of us have a low count and others don't? I don't know.
If you find out, let us know, okay? Because I have the same questions you do!
