Cystitis is an inflammation of your bladder that causes pain and a feeling of frequently needing to urinate.
Interstitial cystitis causes chronic, reoccurring pain meaning your symptoms continue over a longer period – sometimes months.
The cause of interstitial cystitis is not known but research suggests it may be inherited meaning someone in your family had the condition. Both men and women may experience interstitial cystitis.
Your GP may diagnose your symptoms using a sample of your urine. They may also order an ultrasound to view your bladder and assess any irritation.
You may also be referred to a specialist for a cystoscopy.
