Thanks to all that have written on this subject. About 3 years ago I had an epsiode and went to the ER. After a day of every test known to man it was determined they did not find anything wrong and it would go away which it did after a couple of days. Two days ago I woke up with it again and went to the Urgent Care. They did a battery of tests and again could not find what was causing it. As of today it has pretty much passed and hopefully it will not come back for another 3 years. I did have the upset stomach and was also given the same prescription as had been mentioned in other notes and it did help.
After reading as much as I can on the subject it could be the ears, dehydration, etc, But it appears to be non serious and totally uncomfortable.
