That's totally a UTI!

There is a cranberry extract pill that helps the pain. I can't remember what it's called, but as ZH said, sugar makes it worse so the pill is a good solution for that.

1/2 a day after you start the antibiotics, you'll start feeling better. Be sure to tell your doctor if you're allergic to sulfa, because that's a commonly used drug for UTIs (and it sends me to the ER if I get it prescribed accidentally)
