A doctor would have to tell you for sure. If you have anxiety, try and take a deep breath and relax.
I suffer from it also, and chest pains are one of my symptoms. Not very handy!
If you are experiencing chest pains, shortness of breath, or any other symptom, see your doctor about getting some tests. You may have to see a cardiologist. I have had a couple of stress tests, nuclear imaging, ekgs and echos. I'm deemed cardiac healthy.
