Hello. I was diagnosed with Acid Reflux/Hiatal hernia/IBS years ago. I have suffered off and on. Have been put on numerous meds to try and help me. Just recently like a month ago, I started having this lump feeling in my esphagus and my food gets stuck there. The Doctor put me on today, carafate to see if this will help. I am having a Endosocopy and colonoscopy this Friday JAN.9TH. I am terrified. I just hope its nothing really bad. The last tests back in 2005, they suspected Barrett's but after the pathology tests were done, it came back no! But now things feel worse than then so I am very worried.
