This type of reflux can be acid or the mucus... sensation of post nasal drip. You can find more by searching for silent reflux or laryngopharyngeal reflux (LPR). I had regular acid reflux for many years from a sliding hiatal hernia. Because of the surgeries I had I now have the silent reflux. I also have allergies and sometimes it is hard to figure out which is happening. The silent reflux can cause damage to the esophagus and throat. So yes, get it checked out. Small meals.. several of them a day, watching what I do eat and prilosec help.
