Wouldn't refer you to a PT? Bogus. I'd get a new doc.
I've been working with a chiropractor, an endurance sports-specific guy, who's given me some good exercises and stretches. It is starting to get better, slowly. I did have to cut back on training, and that's a drag, but if I get better in the long run, I'm not worried.
It doesn't hurt during cycling at all, luckily. Afterwards, well...I have decided to lay off the big hills for a week or two. Strangely enough, walking a 5k really *$#@ed it up.
