Bladder Pain Syndrome
Understanding persistent bladder or pelvic pain, how it is investigated and the different ways your healthcare team can support you.
A guide for patients and carers
Understanding the condition
Bladder pain syndrome is a long-term condition that causes pain or discomfort around the bladder and pelvis. It is also known as interstitial cystitis. Symptoms can fluctuate: a more difficult period is often called a flare-up. The condition can affect sleep, work, relationships and emotional wellbeing.
Symptoms you may notice
You may feel pressure or pain that becomes worse as the bladder fills and eases for a while after passing urine. Some people need the toilet often, including at night, or feel urgency even when there is little urine in the bladder. Pain during sex can also occur.
Similar symptoms can have other causes. A GP assessment is important, particularly when symptoms are new, changing or not improving. Having bladder pain does not by itself confirm a diagnosis.
How is it diagnosed?
There is no single test that explains every case. Your clinician will review your medical history, ask about the pain and examine you as appropriate. They may ask you to record drinks and toilet visits in a bladder diary. Describing what happens before and after passing urine can help build a clearer picture.
Urine testing can look for infection and other abnormalities. A urine culture identifies bacteria that may need treatment. Depending on the findings, a specialist may consider a cystoscopy to look inside the bladder or tests of bladder storage and emptying. These investigations help rule out other explanations and guide care.
Building a care plan
Treatment is individual, and you may need to try more than one approach. Your plan may include medicines for symptoms, specialist pelvic health physiotherapy and support with managing pain. A clinician may discuss bladder treatments or procedures if appropriate.
Physiotherapy for bladder pain may focus on relaxing tight pelvic floor muscles. Do not assume that repeated strengthening exercises are right for you; seek advice from a suitably trained physiotherapist.
Managing symptoms day to day
A short diary of symptoms, food, drinks and activities can help you and your clinician identify possible patterns. Discuss changes that seem useful rather than making many restrictions at once. Ask what level of fluid intake is suitable for your health.
Gentle activity, relaxation and emotional support may be useful alongside medical care. Let your team know how symptoms affect sleep, intimacy or mood. Agree how treatment will be reviewed and what to do during a flare. A symptom record can make it easier to explain what has changed.
When to seek urgent advice
Contact your GP urgently or NHS 111 if you have blood in your urine, or bladder pain with a high temperature or shivering. New signs of infection or a significant change in symptoms should be checked even if you already have a bladder pain diagnosis.
