I have frequent urination, it started when I was 8. Now I'm 20 years old and I'm still experiencing it. I don't feel any pain during urination though, it is just the time interval that bothers me - it's too frequent. I've had urinalysis but result showed all is normal, same goes with my ultrasound, my organs are normal. What could be the possible underlying cause of this? Please answer. I really want to live 'normally'.
