For urine issue and pressure. Urinate.

Since February issue started with stomach pain and frequently urine and pressure and pain. I need to urinate almost after 1 hour every time but not in night. And also I need to wait a minute or more before passing urine with pain.  I consult for urologist, kidney function test done. Urine test done.  Pre and post void done stomach ultrasound done, cbc done, all normal, but in uroflowmetry he said little obstruction. And he gave 30 day urimax 0.4 capsule and pre and probiotic capsule. And he said if it will not work have to test using durbeen... I took all medicine for 1 month, but I am facing now is when I drink 2 glass water in one go, need to urinate after every 1 hour 2-3 baar, and then in whole day I urinate 7-8 times, I took only 7 glass of water from morning to sleep... But I am facing the issue of pressure and pain in my private parts and also it hurted before voiding and sometimes I have to wait few second before voiding although I feel to urinate.
