I m having a lot of pain when I urniate, a lot of kidney stone symptoms, but I took a urine test and I had no infections, and also took a cat scan and no kidney stones showed. I m only 18 years old. Also when I get hard I feel a pinch underneath my penis. What can this be ?
Hello, You don't have a stone in CT scan and urine test also normal. So kidney stone could not be possible.  You should be investigated further with urine culture report to check any infective organism if present.  Chat Doctor.  If this problem remains constant then you have to consult Urologist for your physical examination.  Hope I have answered your query. Let me know if I can assist you further.
