Thanks to all for responding. The diarrhea seems to have resolved. Unfortunately, so has the little blast of energy that I had for a few days last week after I started the new ABX regimen. Now I'm back to fatigued although I'm sleeping pretty well. Most noticeably, my joints and muscles are really aching. All of my usual achy places are aching even worse than usual and, as I read on a Bartonella thread, my back aches like I pulled muscles even though I haven't. I called and left a message for Dr. J to ask whether this was probably a herx reaction and his nurse called back to say yes but I didn't expect anything different. I'm very skeptical about
this whole DX, the treatment, and Dr. J. I'm wondering - do ABX cause significant muscle and joint pain in the absence of infection?
