I have tested positive for MARCoNS and tried BEG spray but developed tinnitus almost immediately. This was back in May. I still have tinnitus. I think the MARCoNS is pretty serious as it feels like it has gotten into my jawbone and teeth. A month after my jaw started hurting, I developed neuropathy. I am sure this is related to the antibiotic resistant staph, which is what MARCoNS is. I tried just EDTA spray and colloidal silver. Nothing is working. My doctors are not willing to try a different antibiotic that the MARCONS is sensitive to. I am not willing to use a fluoroquinolone on this. Anybody else have this happen to them? I think the MARCoNS is causing the neuropathy because it improved after I took oral Bactrim and oral Doxycycline, both tested sensitive on my MARCoNS test. However, now the Bactrim is testing resistant. This is really making me nervous. Any ideas? I am still on doxy trying to keep MARCoNS at bay.
