Hello, I'm back again. Still hasn't cleared up, although it did go away for a while (several days). No new symptoms. It came back when I again forgot to keep drinking water. I found that constricting the urethra helped greatly (temporarily switching from boxers to briefs).
Found this related post
http://www.medhelp.org/posts/Urology/urethra-discomfort/show/1090042, and someone there mentioned that it might be stones?
This will probably be my last post on the matter, as only 1 other person gave it much interest in almost 2 weeks now. I might try another forum or medical info site. All I can say to others is, it's most likely urethritis or irritation from high sugar levels. As for the direct cause, I'm still in the dark. I'm not ready to pay an overpaid doctor yet, as I'll probably get another run-around or expensive "pill". But who knows if this keeps up.
Happy holidays.
