Yes UTIs are painful, well for everyone else lol. Strangely I never have all the painful peeing or having to go all the time, or the blood. I dont even get a fever. So I never know I have one until I am SUPER sick. If you dont get a UTI treated it can become a kidney infection. Which I have had three of. If you think a little burning when you tinkle is bad, wait until you have the pain of a kidney infection. If seriously feels like someone is kicking you in the lower back and sawing you in half at the same time.
