For 4 months I've had extreme burning in my stomach. I have had cameras in my stomach, 2 CTs, stool samples tested, blood work and they can't find anything. The burn becomes unbearable and nothing helps. Some days are worse then others. I sure hope someday they find a medicene for this ailment.
ALOE VERA JUICE....WORKED FOR ME 
AVOID CAFFINE, ALCOHOL, SPICY FOOD, YOUGRT, MILK, LIME, ORGANGE
STRACH, FLOUR PRODUCTS.
DRINK YOUNG COCONUT MILK EARLY MORNING FIRST THING. THEN LOTS OF WATER. BARLY, FRUITS (NO PINEAPPLE OR ORGANGE).
CONCENTRATED DRINKS TO BE AVOIDED.
Try boiling 1 tablespoon of whole flax seeds in a cup of water and drink morning and night to soothe the easophogus and aid digestion.
Flax seeds have a lot of health benefits....hope this helps
