I recently had symptoms of a UTI. Went to my urogynecologist and had a urinalysis done. Results showed no infection. Leukocytes and WBC was slightly elevated but no bacteria found. So the doctor's office told me I could wait a few days to see if my symptoms subside, and if not, to call them back early next week. My symptoms have decreased considerably but the home test says I still have infection. Has anyone ever used D-Mannose for a UTI? I have read that it is very good and will resolve UTI problems. Any comments or advise would be greatly appreciated. The nurse at my urogyne's office said that is symptoms don't subside they would have to take a urine sample thru use of a catheter. Unfortunately, every time they do that, I seem to get a UTI.
