Hi Smoky. I guess I have to say that I'm still a bit confused. Most people can feel liquid going down their esophagus. In essence, your esophagus is a hole...actually a long, open tube that connects your throat to your stomach, so when you say you can feel liquids going down your esophagus and you can feel it going down TO your esophagus I'm not sure what to think.
When you take a drink it goes in your mouth down your throat, down through your esophagus through the esophageal sphincter and into your stomach. It is normal to feel a sensation all the way from point A to point B.
The hole that was found in my esophagus was found during surgery and was caused by the acid eroding the wall of the esophagus. The symptoms of GERD included, for me, constant, severe heartburn, regurgitation, coughing, throat clearing, pulmonary problems and chest pain. Others could be different. The level of acid and the frequency of regurgitation wasn't known until they did the 24 hour ph and the bravo.
The Nissen repaired the hole in my esophagus, stopped the regurgitation, stopped the coughing, throat clearing, chest pain, heartburn and aspiration. The vocal cord dysfunction included chronic hoarseness, throat clearing and shortness of breath, especially while talking. The vocal cords would close when they should be opened and it made it difficult to breathe.
