barrett's esophagus
"A year ago I was given Dexilant on a trial basis after being diagnosed with Barretts.  I immediately had relief for GERD.  My only issue now is that I have had some chest pains that could mimic a heart attack.  I actually went to the ER a month ago to get checked out.  My EKG and heart was normal .  Now last night I experienced the same situation where the chest pain would come for about 5 seconds and subside for 10 minutes or so.  Very disconcerting. I am sleeping better at night and feel much less nausea than before Dexilant."
