When I have to pee my scrotum has a cold clammy feeling, almost like I'm sweating down there but when I check there's no sweat. And after I pee it goes away, I've been to a urologist and he checked my urine and only found something with the acidity that was crystalizing stuff in my urine. I'm going back soon. Are there other tests besides checking urine to see if one has an std or not? I also have had some symptoms that are associated with prostatitis as well as kidney stones and uti's. But like I said, I've been to the doc and he didn't find anything. Had my blood checked as well. Any ideas?
