Yep; I had very similar pain. Here's the stretch I did that helped immensely. Lay on the floor on your back. Bend your knees with your feet on the floor. Then cross one leg over the the other. Lower your legs to one side until you feel the stretch. Hold it as needed. With your legs still crossed, lower your legs to the other side. Hold as needed. Uncross your legs and then cross them with the other leg now on top. Repeat all of the above.

I did this before, during and after rides as needed. The stretch actually resoleved my pain rather quickly.

Hope that helps.
