That's a normal, harmless thing, if it's the same sensation I'm thinking of, which I'm pretty sure it is.

I found this information: precordial_catch_syndrome_chest_pain
an excerpt: It sounds similar to what I experienced, and it's interesting that it says it happens most often in children and teenagers because I remember it being much more common when I was a kid. The only thing is I don't feel any "bubble popping" sensation before the pain goes away, not that I can remember anyway.

OMG! That's it!!! That is totally it!!!! Thank you so much! FINALLY! I know what it is! THANK YOU THANK YOU THANK YOU!

You're welcome! I just noticed that the link wasn't working, I fixed it. But I take it you were probably able to search the term and get some info yourself? Glad to be of help!

I was able to find just that article. Thank you thank you thank you!

Flossing reduces the risk of heart disease.

I've had this same problem all of my life! Now that I'm a bit older (almost 42) I was getting a little concerned since the pain was getting terribly sharp and lasting longer. It was a sudden sharp pain that takes your breath away! I also couldn't take a full breath of air since the pain would seem to be its strongest at the peak of inhalation.

I finally made an appointment with a heart specialist for a nuclear stress test on my heart and was relieved to find out that my heart is in excellent condition! Whew! What a reilef. The cost of the appointment was definetly worth it for the peace of mind.

I don't particularly think this is a random comentary on my life since it directly corelates with the thread. So sorry for ruining your day!
