Generally we don't herx from bartonella like we do for Lyme. With Lyme die-off we get worse before we get better. But some LLDs even say there is no bartonella Herx!
In my experience treating my own bartonella I started off with minocycline and rifampin treatment. At first nothing, no herx at all. Eventually it just reduced my symptoms down!
I also remember when I first got my Nutramedix Houttuynia in the mail. The first thing I did was take 3 full dropper fulls. I wanted to know if I had bartonella by taking the Houttuynia and feeling the reaction that happens in my body. All it did was make my shins kind of burning in pain.
For me there wasn't much of a bartonella herx. Treatment for me just kind of suppressed the symptoms. I don't even know if my bartonella is done!!! LoL. I have no more anxiety, no more insomnia, and no more of those shooting pains, and I have stopped treating it. Hopefully it's finished.
But in my experience and what I know, bartonella doesn't herx like Lyme. Generally treatment for bartonella is pretty quick in reducing the symptoms and treatment seemed to suppress the symptoms within a few weeks. For me within 2 weeks of initiating treatment my bartonella symptoms were pretty much all resolved. BUT when you stop treatment for bart and it is not fully treated, it tends to come back really fast. If you stop treatment and can go a few months without it relapsing, it is probably safe to say it is gone for good. For most people bartonella treatment takes 4-6 months, but longer in some. Fluroquinolones can treat bart in 1-3 months.
