@healthyfungus infection? staff or strep?
Unfortunately I've tried loads of antibiotics and protocols, too, but if the infection goes to the lymph or bone it can be harder to get out -- it flares up during allergy season or junk food binge for me. I'm finally getting rid of it using a machine that can be hard to get/costs a lot of money.
Otherwise, the only solution I've heard that I think works is, essential oil sublingually, which is scary for the burns so I haven't tried it yet -- so far I think this machine is working.
Find a naturopath and ask them to refer you toward an electronic frequency practitioner.
