I just went to a walk in clinic as I smell a sweet ammonia and the Dr. told me I had blood in my urine, I have lower abdominal pain and flank pain I am 57 yrs. non drinker or smoker I weigh approx. 137 Lbs, the Dr. did not give me a perscription, I am usually healthy, but the ammonia (sweet) is awful and it started on my holidays to France and has progressively gotten worse. I am scarred, as my daughter has brain cancer and I need to be well.
