After sex, but sometimes just regularly, I feel like I have to constantly urinate. It s such an uncomfortable feeling, and about a month ago I had a UTI... they put me on medicine for it. And I felt like it didn t even go away. I just currently took an AZO, because I normally feel better when I take those. As you probably know the internet doesn t help with anything, but could I possibly have a kidney or bladder infection, maybe worse than a UTI?
