Which Mayo Clinic? I go to the one in Jacksonville FL. My last visit was in July. I saw Dr. Francis and her NP. I was having a lot of trouble swallowing again and lots of thick phelgm. Dr Wang did an endoscopy and they dilated my esophagus again. I was diagnosed with Barrett's Esophagus. They found mucus in my throat that contained stomach acid. They increased Prilosec to twice a day and that has helped a lot. They did not say LPR or GERDs in voice or in documents. Just said my esophagus is just not functioning well. Food sticks in my throat and most often right before entering my stomach and it backs up. Usually it the food just comes back up, but I sometimes cough or vomit it up. This blog post has a little of my journey.. a basic outline: http://zarogasnook.blogspot.com/2015/08/a-long-time-passing.html .
