Dear Flower
Homeopathy is more complex than "one pill for all",each person might need a different remedy for the same symptoms. But what I can suggest is keep an eye on your PH levels (acid +alkaline levels)
Foods+drinks that cause too much acid also cause this ulcer type symptom. These foods are: red meats,alcohols,dairy,sugars,breads,bakery items,sodas,coffee..........(stop these)

..................A pinch of Bentonite clay or baking soda in your water will reduce this acidity .
