Can't stretch quad all the way?

[kunta]

For the past couple months I've noticed when i stretch out my quads, I can only bring back my leg around around 70% of the way back, if i push it harder then my knee starts to hurt. I used to be able to bring it all the way back and touch the back of my leg. Has anyone had this problem before? Will taking glucosamine with msm help?

You'll need to better explain the type of stretch you are doing.
