Snap, Crackle, Pop

A couple of days ago, I got out of the car and my knee started crunching around. It makes a clunky snapping sound with nearly every step now. So I am going to my orthopod tomorrow. It does not hurt, but it is really annoying. I can not figure it out. Maybe something is floating around in there, or I have a flap that is sticking up from cartilage. Soooooo, wish me luck. I am anticipating that I may have to retire from triathlons.
