After suffering pain in my bladder for over a year now, I had an appointment with a urologist who diagnosed trigonitis. He prescribed antibiotics, one after the other for about 6 months. I felt that I could not empty my bladder and sat in the toilet for ages at a time. I happened to speak to a nurse one day when I was visiting a friend in hospital, who told me to try extra strength cranberry tablets. From that day to this my problem has nearly gone, I can't believe that something so simple can help so much. If I ever forget to take a tablet, a few hours later my bladder lets me know!
