Can a nerve pain drug boost bladder pain relief?

This trial is testing whether adding the nerve pain medication pregabalin to a structured educational and behavioral program can better ease the symptoms of bladder pain syndrome (also called interstitial cystitis) than the program alone. Adults with this condition will be randomly assigned to receive either the program by itself or the program plus pregabalin, with doses adjusted over 12 weeks. Researchers will compare how many people in each group report meaningful improvement in their overall well-being, and will also track pain, urinary symptoms, sleep, and quality of life. The goal is to see if the combination offers a more effective way to manage this chronic, painful condition.
