UTI Gram Negative Bacteria

I’ve always had UTI’S at least 5 or 6 per year. Antibiotics always took care of it. Recently I’ve been getting Gram Negative UTI that’s almost impossible to get rid of. In May I was hospitalized with Citrobacter Bacteria that caused Sepsis and had IV antibiotics. For the past 3 weeks I’ve been uncomfortably dealing with E COLI, ESBL, MDR another Gram Negative Bacteria that won’t go away. I just finished another dose of Fisfomycin and 5 days after I’m experiencing symptoms again. Anyone else have bad bacteria that won’t clear up. I’m really hoping I don’t have to lay in the hospital again with IV antibiotics and all their horrible side effects.
