I have a friend that told me to start drinking black hot tea, no sugar. I had UTI so bad this last winter I was passing blood, ended up having to have two shots and lots of anti biotics, drink lots of water, my urologist told me to save my money on the cranberry juice, just water, alot there is azo pills you can get at the drugstore, they make you pea red but help relieve the pain. hope you get some relief, I would say if it gets that bad to go to the emergency room. The pain is terrible
