<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have been experiencing blood in my urine, frequent urination, rib pain, and pain of the anus. What could be the reason for this?  <response>: Based on your symptoms, it is likely that you have suffered an injury to one or more of your internal organs, most likely your kidney or bladder. I recommend that we perform some diagnostic tests to determine the extent of the damage and the appropriate course of treatment.
