and does it always have to burn when you pee?

Foul smelling urine can also be a sign of a bladder infection, with or without pain upon urination.

Ohh i get bladder infections a lot.
Basically, it feels like you ALWAYS have to pee. sometimes you can't, and sometimes you can sit there (or stand haha) for minutes.
It doesn't burn so much, as just plain hurt. Like your bladder is going to fall out. mine are generally minor, and I've never had to go to the hospital or anything, but if it is burning when you pee you may have bacteria….
