Pain In Knee From Straddles!

I know there is a thread floating around about this, but I could not find it. I get this pain in my left knee after stretching for my straadles. It usually hangs around a day or 2 then is gone. It is pretty strong today. The pain is localized to the top inside of my left knee. ANy ideas or suggestions to help this not happen? Stretches I do go in this order: Sit in straddles. Sit in straddles while pulling up on my heel. Slide hands straight down on the floor while in straddles. Floor Froggies. Wall Straddles.  Thanks for any suggestions!
