Drink some Lemonade. (potassium Citrate) The citric acid helps kill bacteria in your kidneys, helping flush it out of your system. Crystal Light is the best for that.
I have a history of kidney stones and the bacteria from UTI's causes my stones. My urologist told me Crystal Light lemonade, or real lemonade and citrus fruits help with urinary tract. Drink a ton of water to dilute your urine as well. this will help with keeping the pain down and also from it smelling because of the antibiotics. Good luck. Hope you feel better!
Drink as much water as you can. Cranberry juice. Don't drink soda or caffeine. That should help a lot
