Interstitial cystitis, sometimes referred to as painful bladder syndrome, is characterized by pelvic pain, urinary frequency (an increased need to urinate), and urinary urgency. Other signs and symptoms of interstitial cystitis are a decreased bladder capacity, feelings of pressure and tenderness around the bladder, and painful sexual intercourse (dyspareunia). Men may experience discomfort in the penis and scrotum. Signs and symptoms can vary among affected people and may vary in severity.
