my mom is 91 and she has been vomiting alot, Dr. done test and said wasnt worried to much about cancer since she hasn't been losing weight, He ran test and said liver something was high and done an ultrasound a week ago and still havent heard back from him. She had been on nexium for ulsers they found man years age, but after they healed no one took her off of them, so I did when I found out what it does after so long, and put her on natural probiotics. It seemed to help, but she still have vomiting issues and her back hurts real bad. she always had back issues & dr said her back is just plain wore out! I'm hoping it is just worse form the strain of vomiting. What do u think it is and what can I do?
