I am a 36 year old male and tonight I got a very sharp pain in the center of my chest. It feels like it's around the sternum, not inside my chest. It did not affect, nor was it affected by my breathing. The severe pain lasted about 10 minutes and was very scary. Scary enough that I grabbed my cell phone in case I needed to dial 911. The pain was a little more intense if I hunched over. Conversely, if pushed my shoulders back and pushed my chest out, the pain subsided somewhat. My pulse was about 80 (normally it is 60). This was about 90 minutes ago and my chest still has mild pain. I had a simliar episode 6 days ago, although the pain disappeared completely after about 15 minutes. I had one other episode about 3 weeks ago as well. Any help is appreciated!
It might be a good idea to get a thorough check up so as to rule out any possible heart condition. By doing so you will be able relax to some degree next time the pain occurs by knowing that it is a non-life threatening pain and possibly controlled with something as simple as antacid etc..
Hope this info helps.
