Your symptoms merit an answer. Perhaps the best approach would be to seek a second opinion. In some instances when all tests provide normal results, a diagnosis of anxiety is entertained; if anxiety triggers hyperventilation, using a paper bag to breath into for several minutes enables relief when one is breathing the high concentration of carbon dioxide in the bag.
