Bladder pain syndrome (also known as interstitial cystitis and painful bladder syndrome) results in pelvic pain, often made worse when the bladder is full. It may mean people have to empty their bladder very often and wake during the night to go to the toilet. They can experience the strong urge to empty the bladder, often with significant discomfort or pain, and find it difficult to wait to go to the toilet. It mainly affects women.
