I Am 61 Year Old Female. For The Past 4

I am 61 year old female. For the past 4 months I have had extremely stinky pee and also dry, burning eyes. My ophthalmologist doesn't see any issues in my eye and suggested fish oil, more water and vitamin C, but my eyes remain blurry, and painful by the early evening. Otherwise I am very active and healthy (a K-8 principal on my feet and working 10 hours a day).
