My fiance has had heartburn with stomach pain for the past 4 days? - heartburn and stomach pain

went to the DR, which did not even consider or ask questions, just write a script for medication that works at all. I'm worried because it about the food, of course, sleep. As a rule, on the afternoon before dinner, and lasts all night. All ideas what might be? I have tried to investigate the network, but give me the results of cancer me even more afraid for him.
