Hi! I Had Some Acidity And Stomach Problem Like Diarrehea.

Hi! I had some acidity and stomach problem like diarrehea. I than took flucanozole for fungal infection. Next day I started having severe left side abdomen pain, some gas and acidity. All reports came normal. It is little better after 7 days but now I have acidity at a level that it comes in my mouth all the time. I am taking Omez 40mg, eating banana, curd and blend food. But it is not in control. What should I do.
