hurting badly

Hey ladies. It's April 6. I've been hurting since October. It hurts almost every day when I pee. I have been living off of AZO pain medicine that turns my pee bright orange/red. I've been to the gyno and EVERYTHING comes back clear. I've had exams and everything. I've had a CT scan. I'm going to a urologist next week. But has this happened to anyone? I hope I'm not the only one. I'm scared to death and I'm sick of constantly hurting 24/7
