My 77 year old mother who was in great health until 4 months ago when she started have severe acid reflux. This was accompanied by nausea, diarrhea and abdominal pain. Endoscopy showed some slight erosions in the stomach, Barrett's and negative biopsies. I am not sure if they tested for H. pylori. A CT scan was negative, as was abdominal ultrasound. She has been placed on Protinix and is still having daily nausea, worse in the am. She also has occasional loose stools. She is now complaining of muscle tremor in her hands, anxiety and a "weird" feeling in her head when her symptoms are at their worst. She related to me that she would rather be dead than have this constant nausea. Any thoughts??
