My mother started with a stomach virus, diarrehea and vomiting for 2 1/2 days, she did not really bounce back from that 100%, then almost 2 weeks later she started with dizziness foe which was taking Bonine and then her primary care doctor told her she was dehydrated to drink gallons of Gatorade, her dizziness started a week ago this past Sat and she is better now, her M.D. prescribed a motion sickness patch that she wears for 3 days at a time, today she is finishing her 2nd patch. It has helped but she still gets dizzy when she puts her head back, what could this be? All her bloodwork was fine according to her MD as was her blood pressure. She is 83.
