yeah if it doesn't hurt then don't worry about it too much. just keep an eye on it. stretching it out more and maybe starting with one more warm up set could help... it could be that one of your ligaments is not holding you in tight enough.. I would also take some joint supplements just incase you go from snap crackle pop to grind pain and cry. :( . the supplements are Glucosamine, Chondroitin & MSM .. and you can get them at GNC, Vitamin Shoppe and even CVS.. here's one link from BN

and this is another little site I came across that is good for looking up any type of mineral, vitamin and chemical.. it's one of my favs. :cool:
