I had Bartonella, too, but not many visible signs of it. I first took Azithromycin and
Rifampin, but eventually figured out the
Rifampin was causing heartburn and contributing to my chronic stomach pain. I was diagnosed with h.pylori and campylobater shortly after that, but even after they were treated, the stomach pain continued.
After I switched from Rifampin to Levaquin, the stomach pain decreased and the heartburn went away.
