My guess is that morgellons is parasite-bacteria-fungal and maybe heavy metal and virus. Which means it will respond some to some meds.
Now where on your body are you most likely to find a poly-microbial infection?
Core issue is the jaw. Jaw issue could easily be root canal-I offered 2 people 10 grand if they pulled their root canal and it wasn't infected-neither collected. (don't ask Im not doing that people on this board) If I knew you I would bet 10 grand on ever single root canal being infected.
Could be mercury filling, could just be back luck dental infections. Notice how much of morgellons is had related-eyes-scalp.
Zero in on your jaw that where he problem is
