Complete the work up: Get a MRI of the abdomine. One MRI is worth a thousand internists

REFERRED PAIN: If no pathology defined in region of mid epigastrium, then one has to suspect referred pain to this region. When any inflammatory process in the rt lower quad starts in the mucosal region of the bowel, pain is referred to the epigastric region. Only when extension of the inflammation reaches serosa does pain localize to the rt. lower quad. Look for inflammatory process near cecum.
