P.,
Reflux is treatable. Reflux is the backing up of stomach acid into your esophagus.This acid can erode the protective esophageal lining and eventually through. A number of things can cause this acid reflux the most common is a hiatai hernia. I don't know exactly how it causes reflux but it can. The first thing you need to do is see a gastroenterologist, they are specialists in the area between the beginning of the esphagus all the way through the bowel. This doctor will probably want to run tests to determine exactly where the problem is, in the meantime try sleeping with your upper torso elevated 30 degrees, perhaps a recliner. Avoid fatty, gas producing foods (unless you're taking papaya which aids digestion....you mentioned a health food store. Avoid smoking, alcohol and acidic drinks like Coke, Pepsi and coffee.
Your only time reference you mention was a month ago seeing an ENT and I can't imagine WHY you were't referred to a gastro doctor.
I also want you to know that doctors are NOT God. YOU employ them, they work for YOU. YOU pay their salary and you should expect their services to leave you satisfied, all questions answered and not rushed through the visit. If, for any reason you are dissatisfied with a doctor you have the right to fire and find another doctor. Doctors are simply people who chose that profession and are no different than a mom with countless responsibilities or the person picking up your garbage. We all have our professions and jobs to do
Again, P., I cannot stress enough that you see a GASTROENTEROLOGIST about this to make sure it isn't something about to become really bad. God bless you sweetheart. I hope you get some relief.
