I was having testicular pain for 3 weeks so when I went to the doctor for ultrasound it was found that I have kidney stones in both my kidney of the size 3.74 mm and 3.24 mm.the doctor said to drink 7 lit of water everyday and gave me cystone and told that the stones would hopefully pass with urine. I wanted a second opinion from another doctor and please also tell me if I should get some other kind of tests for this.
