My 64 y/o female neighbor has quivering of her hands and arms,an aching up and down her entire spine, and mouth gets dry. When mouth gets dry , she will dry heave, but putting a mint or something in her mouth will totally stop this symptom . There is no preceding nausea. This started 2 weeks ago, with vomiting. No other flu like symptoms, no cold symptoms. She said she would vomit if she ate.
