Infection?: You sound as if you have problems. You have blood in your urine. What tests were done that found no infection? I suggest that you go to an infectious disease specialist and have an echocardiogram done to make sure you do not have an endocarditis. Has a physician been following you? If so, has blood work been taken to see if your kidney function is worse? Go see a physician or go to the er asap.
