hi, I have UTI for almost a week now. I drink a lot of water since then, and sometimes I dilute it with vinegar as I research it's also good for UTI, but i still fell that the infection is still there because it is still painful when I urinate. I don't want to take antibiotic because I don't want to kill the good bacteria as well, I just want to treat my UTI the natural way... what must I do?
