It will be of help if you kindly mention your age and gender and your medical history. Any diabetic history?
In elder males hypertrophy of the Prostrate gland can result in frequent urge to urinate but passing of urine occurs in small quantities every time.
Please get yourself investigated for the following:-
1. Complete Blood Count
