Hi
I have gone through your query, i will try to give you suggestion which will be helpful to you.
In order to provide you with specific answer, I wanted to know your age.
One of the common cause of your symptom is
urinary tract infection, even though you don't have any other symptom.
I would have asked you for urine routine, before deciding on the treatment options. Presently I would suggest you to drink plenty of water, which you are doing, apart from that drink cranberry juice, which is found to be helpful.
I would have done digital rectal exam, to rule out
enlarged prostate, which can present with similar project.
I hope this suggestion might be of some help to you. I will be glad to help you in case if you have any further queries.
Wish you speedy recovery. Take care.
