Has anyone experienced this with treatment. I'm on zith, omnicef
, rifampin and flagyl. I am feel like poo, which could be part herxing, part flare, part side effects. My main concern is this low back pain. It is in the area of the kidneys. After an hour of taking my meds - it starts. I'm also sick at my stomach, headache, tinnitus, the works. I called my LLMD nurse triage line, but it takes 48hrs for them to answer me.
