Elderly mother has times where she throws up and feels nausea then is goes away and comes back for weeks at a time She is 72 years old has had brain surgery to drain a siswhen she was in her forties and has some dizziness caused when she moves her head up and down to fast. Which caused some nausea but not like this. In the last year she has gotten nausea and been throwing up alot more often. She has diabetes but it is undercontrol and she take medication for it and hypertension. I am very worried. Thanks for your Help. Any ammunation you can give me to get her to the doctor would help alot.
