I have 2 and one thats on its way. You may not believe me but stretching is the best thing in the world for them. My doc said staying flexible is number one. Stretch everyday if you can stand the pain. Evenually it gets better and eases. I still have to be careful, but I havent had a doc visit for it in over a year. I've had mine since I was 16 and I'm now 42.
