AHHH the main question. Is the anxiety causing the chest pain or is the chest pain causing the anxiety. Either way you need a doctor willing to find out.
As rls said, what kind of pain are you talking about very specifically? You say they have happened twice. Were they same kind of pain? Same location? Same intensity? How far apart were the episodes? Any other symptoms? Shortness of breath? Dizziness? Pain radiating to your shoulder or jaw?
Do you have an anxiety or panic disorder that you're being treated for? I see you are anxious driving. Does it actually stop you from driving? You're anxious about your finances and the future..........who isn't these days?
We would need to know a lot more about the pain and you and your life before we could say much of anything. But you do know that we are not doctors, right? We cannot diagnose anything.
Your doctor was not concerned about this chest pain so your question is "why should you be?"
My first thought is because it's YOUR heart, not HIS. And when you saw him, had you had both episodes of the chest pain or just one?
As the above poster stated, chest pain can be caused by a great many things that have nothing to do with the heart. Anxiety is one of them. If you take an anxious person, give them a couple of chest pains, their anxiety increases and they get more chest pains and they get more anxious and it just keeps getting worse. These pains are of enough concern to you to write to an anxiety forum about them even after you've seen your doctor. What does that tell you? It tells me that you still have anxiety about these pains. And since none of us here can tell you that they were "nothing to worry about," you need to see the one person who CAN and also help you with your health anxiety and that's your doctor or your cardiologist.
It IS always better to be safe than sorry and it's always better to confront and deal with anxiety before it takes over your life.

What kind of pains are we talking about? Sharp pains, dull aches, any numbness in the arms? Could be any number of things...indigestion, muscle pull, cramp; but anxiety can cause some degree of chest pain but I'm not sure that it would cause a lot of pain. It's worth getting checked out just to be on the safe side.
