Cystitis can cause problems with peeing and make you feel unwell.
Cystitis in adults can cause:
- pain, burning or stinging when you pee
- needing to pee more often and urgently than normal
- feeling like you need to pee again soon after going to the toilet
- urine that's dark, cloudy or strong-smelling
- pain low down in your tummy
- feeling generally unwell, achy, sick and tired
- blood in your urine
In adults, cystitis does not usually cause a high temperature (fever).
But if you have a temperature of 38C (100.4F) or above and pain in your lower back or sides, it may be a sign of a kidney infection.
It can be difficult to tell whether a child has cystitis, because the symptoms can be vague and young children cannot easily communicate how they feel.
Possible symptoms of cystitis in young children may include:
- a high temperature (fever) of 38C (100.4F) or above
- weakness and tiredness
- reduced appetite
Children with cystitis can sometimes also have symptoms usually found in adults, such as pain when peeing, peeing more often than normal and pain in their tummy.
If you're a woman who has had cystitis before, or you have mild symptoms that have lasted less than 3 days, you do not necessarily need to see a GP.
Cystitis is very common in women and mild cases often get better on their own.
But you should see a GP if:
- you're not sure if it's cystitis
- your symptoms are severe
- your symptoms do not start to get better within 3 days
- you get cystitis frequently
- you're pregnant
- your child has symptoms
- you're a man
Children and men should always be seen by a GP if they have symptoms of cystitis, as the condition is less common and could be more serious in these groups.
Cystitis is not usually a cause for serious concern, but the symptoms can be similar to several other conditions, so it's important to get a proper diagnosis if you're not sure whether you have it.
You should see a GP if you have long-term or frequent pelvic pain and problems peeing, as you may have a condition called interstitial cystitis.
