Last year on Mother's Day, I contacted one of your colleagues by leaving a message with an answering service that I had bad heartburn. I received a response about 10 minutes after I placed the call. I described my heartburn telling the doctor on-call that I hadn't eaten anything to have caused it and I remembered having some shortness of breath the night before. The doctor then gave his opinion.
He said, "It could be esophageal, but I can't rule out a heart attack. Take an antacid and if it doesn't get better, go to the emergency room."
