I had systemic parasitic infection- you can look back at my posts - I did three times weekly inhalation with anti parasitic meds plus saline rinses - many daily plus anti parasitic meds rotating them plus did holistic options on off days of meds- took ten months - I saw my doc every two days during that time Best anti parasitic med for me was prazi but overall I think the combo of everything was beneficial. I had hook tape roundworm- I have no or low immune system- the reason I got so ill so fast and so bad. And yes conventional docs thought I was on drugs or a hypochondriac. I was diagnosed with my immune problem after my health improved. Only because I knew my experience was not normal and pushed for info diagnosis on why I had gotten so sick. Now docs take any issue I have very seriously.
