Hope he can get relief soon!!!! If it had not been for peppermint candy, with the oil, I don't know what I would have done. Nausea was with me for so many years. I could not move in any way without starting the nausea, just laying, was my relief. Finally after a diagnosis, Klonopin eventually helped a great deal. Medications had to be very slowly added, because of the sensitivity. I hope and pray that he gets better soon. Nausea is usually the low blood pressure, but I have been told that everybody is different, but at the same time, alike. As we get better, so due most of the symptoms. Dizziness and fatigue are still with me, when I am too active. Your son is very young, so he has a reason for a lot of HOPE.
