Hi. My doctor discovered I had iron deficiency anemia, and started me iron tablets last Thursday. By Saturday I was having mild UTI symptoms. Today, Tuesday, I am having severe burning when urinating and also having to urinate frequently but only urinating like a teaspoon or two at a time. Lower back is hurting, but not much. I took a home uti test and it was positive. Did the iron tablets cause the UTI, or did the UTI possibly cause the iron deficiency? Do I need to go and see my doctor for treatment, or should I just start drinking cranberry juice and lots of water?
