Dear Mike,
Making diagnoses over the internet can be frought with hazard and we tend to be very conservative in this area. There are many things which may cause chest pain including heart related conditions.
Amongst the cardiac causes of chest pain are: ischemia (due to blockages - including both stable and unstable angina and acute heart attack and coronary artery spasm), pericarditis (inflammation of the sack around the heart), myocarditis (inflammation of the heart), cardiomyopathy (heart failure) and rarer causes such as coronary artery dissection, acute rupture of the heart and valves and infections of the pericardium.
Gastrointestinal causes of chest pain include reflux (acid from the stomach washing back into the esophagus), gallstones, esophageal spasm, esophageal rupture, varicose veins of the esophagus, strictures of the esophagus, tumors of the esophagus and other less common GI problems.
Pulmonary (lung) causes include pneumonia, pulmonary embolus, pneumothorax, pleuritis and bleb rupture.
Other potential causes are aortic dissection, back and spine problems and musculoskeletal (muscle strain, rib fracture, etc.).
Psychological causes of chest pain are common and include panic attacks, anxiety, stress and mental duress.
As you can see the list of potential causes in long and may take a little bit of time to determine the precise cause. A good Internal Medicine doctor should be able to work through the potential causes of your symptoms.
Thank You Tessie
