I get this burning sensation in my stomach after eating sometimes not often but seems to be happening more now then it use too?

Stomach pain: The most common cause would be gastritis which is inflammation of the stomach lining. Another possibility is stomach ulcer. Please see your family doctor to have appropriate tests run to rule out these conditions and anything else that your family doctor thinks would be appropriate. If you develop any severe abdominal pain that lasts for four hours then go to the emergency room. If you develop any black and tarry stools or bright red blood per rectum consider going to the emergency room also.Best wishes.
