I have frequent urination and an irritated bladder too, and my kind doctor gave me an old recipe that's meant to help. She says nobody has been able to work out why it works, but it does.
1 cup pearl barley
1 litre of water.
Put water and barley in a saucepan. Simmer, covered, for 30 minutes.
Store in fridge; keep for no more than 48 hours.
Drink 3 cups a day.
You can warm it, if you think it tastes better that way.
I hope this helps!
