I am a 23 year old male and I have been experiencing frequent urination for about 3 years now. I urinate about 20 times during the day and I am forced to wake up about 5 times during the night to go. There is no pain during urination but I never feel fully relieved. I've been to the countless doctors including urologists who were unable to diagnose me. I've taken blood tests, urine tests and sonograms which have all indicated no problems. I have no idea what else to do but I know I can't live with this for the rest of my life. Any help will be greatly appreciated.
