Pain Just Below Belly Button

I have had stomach pain for about a year. About 4 months ago I went to my dr. He scoped me and found some ulcers and a little barrett's esophagus. I have been on prilosec ever since. I feel MUCH better, however, just below my belly button I have pain/discomfort whenever there is any kind of pressure on it. Since it is below the belly button, is this part of the stomach or intestines? The pain does not bother me unless there is pressure there, but it will not go away. I have search the internet up and down but I cannot find any info of what this may be. Can you please give me ANY kind of advise as to what this may be or what my dr may suggest for me?

Thanks!
