Ditto the "see a urologist". My similar symptoms turned out to be kidney stones and required (in my case) surgical intervention. By the way, if you go this route, you'll most probably require a spectroscopy somewhere along the line. Take my advice and get a urologist who will allow you mild sedation during the procedure. I won't kid you (if your a male) this is as close to male childbirth as I can imagine. The best part of it however is it's fairly brief duration, a minute or two. Good luck.
