question: How likely is a UTI to go away on its own? I have one that came on suddenly yesterday. I went to the walk in clinic today but their list was full, and I have a heavy work week starting tomorrow. My symptoms have backed off considerably since yesterday; they are very mild today but still present. I am taking cranberry pills and drinking lots of fluids; last night I took 1 teaspoon of baking soda dissolved in water, which seemed to help. Could I fend it off this way? I'm covering shifts for my boss who is away this week so missing work is not an option, and the clinics where I live have really lousy hours.
