Hello there everyone, I am an american guy in japan with a japanese girlfriend who is has been having some bladder problems recently. Of course she went to the doctor here and they did bacteria tests on two seperate times, but the results were both negative for any bacteria. She has the feeling like she has to urinate, like someone is squeezing her bladder but nothing is released. She doesnt have any pain either, just the feeling of having to urinate, sometimes for 4 hours straight! Anyone have any advice? The doctors here have been telling her it is just a mental problem such as stress. Any help anyone can give will be very appreciated! Also I read all the related topics to this on this site but couldnt find the exact same problem...
