I had it put in on 9-27-10 and today it burns really bad to pee and I don't know why. And I haven't tried anything because I don't know what to do.

You should really see your doctor. We can't really give a diagnosis over the internet, we can only guess and guessing won't give you the answers you need.

Make an appointment with your doctor and tell him/her what's going on.

Good luck.
