Dr. OOT: Has anyone ever experienced Tietze's syndrome?

[Los Feliz Slim]

I've had chest pain for about three days, but it seems to not be associated with my heart. Basically, I feel like I need to "crack" my sternum as I crack my knuckles (my sternum does indeed pop once in a while). I can make the pain go away or feel more sharp based on how I'm sitting, the position of my arms, etc. It hurts to press on the top of my sternum.

Clearly if I thought this was serious I'd have already seen a doctor, and if it doesn't go away by Monday I'll get my ass in there, but I'm not going to the emergency room for a sore sternum.

Anyway, I looked it up and found Tietze's syndrome on wiki. It sounds exactly what's happening here. Anyone have any experience with this?

No, tuq, my wife did not back into my sternum.
