Spasm of the esophagus, muscle spasm, asthma, bronchitis are others that can cause a feeling of pressure in the chest. Do not self-diagnose this one; for chest pressure lasting over 15 minutes without clear cause esp if smoker, diabetic, family history of heart attack, high blood pressure or high cholesterol, call 911.
Can be serious. If due to heart disease, can have heart attack. Can be due to lung problems. Can be due to esophagus problem.
