My age is 26. I have frequent urination problem and slightly pain in left kidney from 6 months.  This is caused due to I was holding the urine for long time and drinking too much water, My urine test report is normal, there is no stone and bacteria. And USG shows right kidney and liver is mildly enlarged.
