Thanks for your question.
Before coming to any definitive diagnosis I will like to ask you certain questions.
Does the burning sensation increase or decrease on taking food?
Is it associate with Nausea
How is your Bowel habit?
Did you ever pass blood in vomiting or stool?
Are you Alcoholic or have habit of taking NSAID's for Headache/Backpain?
My advice to you for now will be avoid spicy or junk foods.
You may take antacid
gel for relieving your symptoms.
Wish you and your husband best of health.
