[quote="guest ee"]i've had similar experiences of most of you. My sternum cracks when I stand up straight after a long bout with the computer. This has been happening for over a year now and I have had no problems and no pain with it except for the horrifying sound it makes.
But, for the past 3 weeks now, I have felt like someone's hand is on my sternum pressing on it constantly. It felt as if my pulse was racing and I was getting kind of dizzy when I stood up.
I finally went to the neighborhood medical clinic that sunday, told them about the heart problems that ran in my family and they gave me an ekg and a blood work-up. Everything came back normal and they told me to come back if it gets worse. Sooo...That friday, I couldn't handle it anymore and went back to the clinic and asked for a chest x-ray. The doctor (different doctor) looked at me like I was crazy, but did it anyway. Of course, he didn't find anything and wrote it off as "panic attacks" and sent me on my way.
At this point, I became pretty upset, because i'm not crazy and I know my body pretty well. I couldn't stand that a doctor was writing me off like that. All the symptoms that you have are the same as mine! I just don't have the "pain" associated with it, just constant pressure.

your post could have been written directly by me! It's spooky how identical our experiences are; if I sit on my couch for a while and stand up, arch my back and pull my shoulders back, it sounds as though I have fireworks snapping off in my chest. It's a brief relief but the pressure is always there as you mention. It also feels as though I have a slight pressure right below my adam's apple in my throat.
I too have had x-rays and they've found nothing. I too have had heart palpitations especially when my sternum is particularly irritable, and I feel dizzy from time to time. My Dr. Has said it's all part of chostochondritis, though it seems odd that inflammation would cause such other symptoms.
Finally, it's a huuge relief to know that i"m not the only one with these symptoms and problems. Close friends can't believe the noises my sternum makes when it cracks, and some doctors just think i'm blowing it out of proportion.
Thank you all for sharing your stories and providing some comfort amid the pain.
