Acid reflux.It is 24/7 since December 2017.I have been on protonic,carafate, dexilant all at same time with no relief. I tried GI Encaps,probiotics 50 billion and 16 strains, digestive enzymes. I am considering the LINX procedure when I switch to Medicare G the 1st September. I have an extensive health history.My other insurance has left me with numerous bills. Will be 65. I have questioned whether I should go to Mayo or what to do.I have developed 75 food allergies so I try to do chicken soup, oatmeal, potatoes and eggs. But also allergic to these foods. Drink water. I am suspicious I have low stomach acid since I did a baking soda test. They say cold stops secretion of acid. I am at a loss what to do.I am so tired of this. I would like to lay flat one night and sleep more than 4 hours at 2 hour intervals. I have IBS with bile stools 5 minutes after eating or taking pills. Any suggestions?
