I'm making a whole post of this because it's too important to ignore in my condition. I just got tested positive for Blastocystis Hominis and I suspect I caught it from my girlfriend last summer, around the same time as my bad flare up which still continues. My flare up involves neurosensory and psychitric problems though, NOT gut issues. I have no idea if I should treat it or not. My doctor thinks Blasto is not pathogenic. I think I want to treat it because the fact that my relapse happened half a month after I met my girlfriend is too big a coincidence. Doc's going to put me on Flagyl if I do convince her. Is Flagyl a harmless enough drug that I can take a chance on and see if it improves my condition, or is it one of those bad antibiotics like Fluoroquinolones and floxies that will destroy me? I know it'll kill everything good in my tummy, that's not what I'm talking about because I can always replenish with probiotics. I'm talking about something more menacing like the type of damage Fluoroquinolones can do. I'm already taking Saccharomyces boulardii to weaken the parasite, but want to take the next step and try to eradicate it. Is it worth it?...Especially considering the low rate of eradication this parasite's known for no matter what you use?
