Is embarrassment worth your life? Don't worry about what medical professionals think because many have told me "we would rather you come to the hospital to be checked than for you to ignore symptoms and end up dead". This is how hospitals SHOULD see it. Never worry about what others think when it comes to your life, you only get one shot at it.
Symptoms like you are describing should never be ignored. And you should not be embarrassed when seeking medical attention for that. Better to rule out anything cardiac than to sit and "ignore" them. Take care, Ally
First off, you should always head to the ER if you think you may be having a heart attack, it's not worth risking it. Although you should be reassured about your prognosis, I wouldn't take a chance before you see your PCP.
Having said that, your symptoms are also consistent with a gallbladder issue or an esophageal spasm which is fairly common. The fact that your pain comes on at rest and not under exertion as well as the fact it has gone on for over a week is very atypical for chest pain due to a CAD.
See your doctor as soon as possible but don't take an y chances.
Good luck,
Jon
