Hello Ganesh and thanks for the query
In my opinion its better to consult an urologist
and get your detailed investigation done and get to a diagnosis. The investigation you may need are IVP, CT scan
KUB, Investigation to rule out Tuberculosis
or any evidence of Ca.
Till you got your consultation take plenty of water as you are already taking with some alkaliser.
Also needs to investigate for other cause of pain in abdomen.
