Its been happening for the past like 3 years as far as I can remember.
Every so often (about once a month, sometimes more, sometimes less) I have to urinate like 20 minutes between each time, and after like half an hour i'm bursting, but it normally only lasts a couple of hours max, then it will go again for about a month. Its also very clear urine when it happens.
There are no other symptoms and I have never had sex.
Any idea?
