I've been having this real sharp chest pain today that stops me in my tracks, pain is at center of sternum. The pain only last for about 5-10 seconds but feels like a knife tip stuck me. I use to get them on my right side but today was the first experience at center of sternum. No pain elsewhere, nor does it move. I've counted some 10 episodes of this today and each has subsided in pain level, but I'm a bit worried about it. Seems the closest I could find on the net matching my symptoms is something called "Precodial catch syndrome", but even that isn't an exact match. I'm 41, average weight, smoker, I've been working out in a gym now for 4 months and these pains NEVER took place while exercising. First attach I got today took place about an hour after the gym and while resting. It bent me right over in my seat. The last attach I just had I forced myself to breath while it happened, no problem so the shortness of breath issue during the pain is not there. It's simply a sharp pain. When they first started, maybe 2 years ago I got maybe one a month on my right side breast area. Today has me scared since it's center and happening allot. Wife is bugginh me to go to ER but a number of factors are causing me to resist it. Any thoughts?
