It is good to start with a blood test or a CBC test to make sure there are signs of infection or inflammation. You also need to take a normal X-ray to check for damage to your esophagus. You also need an EKG and an electrocardiogram panel to check the balance of your heart's health and body fluids.
Doctor, I feel like I'm in my chest, and I can't swallow it, but I think I'm going to have to do some esophageal tests.
