Interstitial cystitis (IC) is a term used to describe the condition of bladder pain or discomfort with a frequent and often urgent need to pass urine. Nine in ten people with IC are women. People with interstitial cystitis may have a bladder wall that is inflamed and irritated (red and painful). In severe cases, the bladder wall inflammation can scar and stiffen the bladder so it can’t easily expand as urine fills it. Some women get pinpoint bleeding of the bladder wall when it is stretched or have ulcers or fissures of the bladder lining which may lead to pain, frequency and urgency. Painful Bladder Syndrome (PBS) is another name for the condition when there is no abnormality visible in the bladder. Bladder Pain Syndrome is the name suggested to include both IC and PBS.
