I have upper abdomen discomfort that put me in the ER about a month ago. I was diagnosed with Barret s Syndrome (sp?) of the esophagus. I was given Prilosec. I continue to have pain and now it seems to radiate under my breast however my whole upper abdomen feels sore. Mammogram normal, cardiac cath ok(had a false positive stress test). US of liver and abdomen normal (last month). Is this all related to Barrets or should I go to MD for more testing? I also fell very fatigued when I have these episodes. A few weeks ago the pain was so bad I almost went to the ER again but it subsided so I didn t. Any ideas?
