Old rib and chest pain ramped up?

3 days after stopping my rifaximin, I've had these sharp crushing pains right under my rib cage and chest. This was never a symptom contributing to my sibo nor is it new. I've had these pains in the past when I "first got sick" and was 1 of my first symptoms among the rest. Rifax made me feel way better gut wise and way less fatigue actually. I'm thinking the rif knocked down or kept some of my Lyme and co infections like bart in check. If I stopped taking the rif and I'm having gut issues again, can this ramp up other symptoms like a flare?? Seems like many flares of old symptoms since stopping the rif.
