This is Mike Berstein from ENT & Allergy Associates in Sleepy Hollow and Yorktown. You know that sensation of a post-nasal drip where you feel like you have phlegm in your throat? Oftentimes it's not coming from your nose, it's actually coming from something called Silent Reflux. That means acid comes up to your throat and that causes mucus. The only way to diagnose it is to come in and see us, we'll be happy to see you. Thanks.
