Other symptoms can include finding it difficult to pee, urinary incontinence and blood in your urine (haematuria).
These symptoms can sometimes be caused by other conditions, such as cancer of the bladder. This is why you'll need a range of tests to rule out other possible causes before BPS (interstitial cystitis) can be diagnosed.
