Could bleeding be a symptom of Barretts?

  I have Sjogren's Syndrome (approx 12 yrs), diverticulosis, and GERD (1-1/2 yrs).  The acid reflux has been controlled well with Prevacid.  Last year I had an episode of spitting up blood for a couple of hours.  It was not coughing or vomitting, rather it was just a sudden warm flow of blood that came up my throat with no pain.  I have had x-rays, upper GI, swallowing studies..and nothing was revealed other than some reflux.  I had an endoscope performed several years ago, when I was diagnosed with the Sjogren's.  This was extremely painful, which was surprising to the MD.  I had severe throat pain for 2-3 weeks after this.  My GI doctor wants to do another scope to r/o Barretts.  I am very afraid to have the scope done again for fear of choking or it getting stuck.  I have a very narrow passageway and a very dry mouth, which causes swallowing problems.  I am unable to swallow most pills.  I have a dull ache under the right breastbone area intermittently since the bleeding episode.  Does this sound like it could be a Hiatal Hernia?  Could this be a symptom of Barretts?  Have you heard of this type of bleeding before?  Are there any other types of non-invasive tests that could be performed in order to avoid the endoscope?  The doctor I am seeing says there is really no treatment for Barretts.  Is this correct?  Thank you for your time.
      
Dear Bonnie,
Your symptoms are consistent with a diagnosis of gastroesophageal reflux disease and esophagitis (inflammation). Complications of esophagitis include bleeding from inflammation, narrowing of the foodpipe or a stricture and changes in the lining of the lower esophagus called Barrett
