Yes, you can definately herx on amoxicillian. I was put on 1500mg a day for a bladder infection and had a really bad herx. This is how I found out that I indeed had Lyme Disease. EVERYTHING got worse for me especially my joint pain. I couldn't even get out of the bed. Old symptoms came back too like anxiety, floaters, etc. And I also had new symptoms. This lasted for about two weeks for me but I noticed that the pain was diminishing at the end of those two weeks. Of course, the pain is back now but I'm currently not on antibiotics yet. I'm detoxing my body and getting it ready for the antibiotics.
2003 symptoms started with very intense panic attacks and anxiety. Also had sound and smell sensitivities. Was in and out of the hospital from 2003-2005. Diagnosed with panic disorder.
2007 found an LLMD and was diagnosed with Lyme. Didn't start treatment.
2008 symptoms came back with a vengence. Muscle pain, joint pain, floaters, stiff neck, rib pain, slow thinking, brain fog, etc...
2009 went back to see LLMD. Diagnosed again with Lyme plus co-infections....Babesia and Bartonella.
