@leec1 That is understandable. Did he offer any other solutions or tests? I am not sure where you are located, but if Mayo Clinic is an option for you, they have experts in diagnosing and treating unexplained chest pain.
You can call one of Mayo Clinic's appointment offices in Minnesota, Arizona and Florida or request an appointment online. Here's the contact information http://mayocl.in/1mtmR63 The appointment coordinators will ask questions to help direct you to the best specialist, either at Mayo or closer to home.
