Anxiety: symptoms are not a sign of illness, they are the mind's ability to produce the "flight or fight" response which gives rise to many physiological changes include chest pains, parasthesia, dry mouth, aphasia, tremor and sweating. Depending on the cause of your anxiety symptoms, your health care provider can recommend appropriate treatment.

Usually, you go to: an MD to eliminate a dx of cardiac problems, just to be sure. If you have panic, and its chronic, chronic chest problems can follow, but again, this needs to be diagnosed with a little more depth. Psychologists and psychiatrists are good at this. Here's another source of info: http://www.psychologyproductsandservices.com/page2.html

Unlikely.: Could be peicarditis or chest wall pain unless you have strong family history of heart attacks. Your chest wall muscles can go into spasms with stress or anxiety and makes you feel chest pain. Other causes of chest wall pain are costochondritis and intercostal neuritis. See your doctor for may be couple tests and pain medication.
