I have been told I have kidney stones. I had pain in my back for a long time, that subsided and now I have a sensation like a UTI when I have to pee, and just for a little bit after I pee, but it doesn t last like a UTI would, so I m assuming its the stone that has moved into my ureter.... is there something I can take to help break it up, and/or could it possible be sludge?
