Could be any of the following -
Peptic ulcer
Bile reflux
Indigestion
Rawness in the stomach i think means that some of you stomach lining has gone- Have you been throwing up alot resently?- So saying this all it means i think is that your stomach is more sensitive to different types of foods mentioned by KORY68 like citric fruits and soft drinks.
Hope this Helps

Burning oozing sensation maybe? Do u have ulcers? or does it happen when eating citric fruits or drinks or pop?
