For several years I have been troubled by a feeling of an internal
vibration located in the chest, somewhere near the heart. I have undergone extensive heart-related tests, endoscopic examinations, and a variety of other non-invasive tests including sonograms to exclude aortic abnormalities...which ruled out the esophagus, heart, abdominal muscles, and the diaphragm as culprits.
This "vibration" started shortly after an ear infection (which was not bacterial)...
