Answer: My first UTI spread to my kidneys within 24 hours. I didn't even know I had a UTI. It didn't burn or anything but I kept having to urinate every 2 minutes. I woke up in excruciating pain in the middle of the night and went to the doctors asap. He gave me Cipro and it was gone by that night.
From my experience and other stories, kidney infections are very painful and you would probably know if you had one. I would go back and get another antibiotic. answers.yahoo.com
Answer: If you treat the UTI with prescriptions, it normally will clear up a kidney infection, but you need the doctor to tell you if it is or not. Treating a bladder infection before it gets into the kidneys is what a doctor like to do. An untreated bladder infection can definately travel to the kidneys very easily. Sometimes a doctor will have to use a different antibiotic if the kidneys are involved, because the infection can be hard to treat. I have had to use several different antibiotics to get a UTI cleared up. Kidney infections are painful and cause pain in the lower back (usually on the sides of the back) fever, nausea and vomiting. You will know if you have a kidney infection. If you have a UTI and are being treated with antibiotics, be sure to take them all as prescribed. Get a follow up from your doctor to make sure it is gone..... answers.yahoo.com
