Sensitivity to scents/smells. Head feels swollen

Hydrogen and IMO. Whole body numbness, sensitivity to all scents(candles,laundry, everything with a scent). Tinnitus/muffled hearing. Reactions to all foods,meds and supplements. Barely surviving any input is appreciated. Just diagnosed with SIBO/IMO. Hydrogen reached 102 at 90min methane 11 at 90 min prescribed xifaxan and neomycin but have ringing in ears so not comfortable with neomycin. Was switched to just Flagyl 250 x 3 for 10 days. Losing my mind scared have so many symptoms and inflammation throughout my body. Autoimmune diagnosis now… Can SIBO cause all of this or systemic inflammation and can my life change with the antibiotic course(flagyl). Please help thank you
