The symptoms that you are describing can be caused by rapid breathing (hyperventilation
) with or without low blood calcium. Is it possible that you were breathing heavy (like sometimes one does when nauseated) before this things started at that particular time. heavy breathing reduces carbon dioxide levels in blood and irritate nerves to cause this symptoms. These are transient and are relieved sometime after the heavy breathing is stopped. It is also a good idea to get you calcium levels checked.
