We have found a Naturopath (very very expensive - we don't know if his fees are out of line or not, but 500 an hour seems a lot!).
Rick has an appointment to see him in August after an initial interview a week or so back. The Doctor is an infectious disease specialist, who knows of CPN, the other Doctor we were working with and perhaps Dr.'s Stratton and others.
During his conversation with Rick, he mentioned that IV antibiotics (infusion) - with a port installed, may be one way he will recommend going.
