I am having serious problem in my abdomen. It pains a lot during the day time like between 12 PM - 8 PM. And it stops paining suddenly after having dinner. I have visited a doctor about 4-5 months ago, they told me its a simple gastritis. They give me medicine for about a 4 days and the pain get relief for few weeks. Again the pain continue about a day in a week for 2 months. No any pain in last 2 months. But severe pain since a week. What is the reason behind it?
