It's almost legit scary, how similiar our situation are. I am 29 years old male, suffering 7 years with IBS, SIBO(only thing I'm officialy diagnosed with), dysbiosis, tongue stuff etc. + in my case also constant pain of teeth. That constant pain in teeth and abdomen are my worst symptoms, and I tried everything too, I'm at the end of my rope. I tried western medicine, eastern one. Nothing helps, but pain is constant, it's not getting worse with time. I'm trying TMS for few months but still I don't have even 1% improvement. Maybe it's some sort of gut imbalance, as all those symptoms happened after few months of anti-biotics for acne, I don't know.
