I posted a question before about kidney stones that I have. I have 2 stones in my left kidney one 5mm and the other 2mm. I haven't had any problems with them in about a month and then last night out of no where I start having left sided flank pain and passing a lot of blood in my urine. I ended up going to the hospital for the pain. They did another CT scan and told me that the stones had not moved at all from the last CT. They gave me a shot of Torodol and sent me home. I was miserable for the rest of the night. How is it possible to have that much pain and blood in my urine if the stones are still in my kidney and have not moved?
