UTIs can happen from anything. I have had about 6 myself, the last one I obtained from being in a hot tub! The best way to describe how those feel is it constantly feels like your bladder is full- even if you don't have to go to the bathroom, you feel the need to pee, and it hurts. While I am not a doctor, it does sound like something isn't right, and if you feel different, then there probably is something going on. I would suggest making an appointment with your doctor or possibly going to your local urgent care (not the emergency room, just urgent care). They have the equipment to run tests for things like UTIs and they are not nearly as expensive as the ER. Hope this helps!
