Sinuses and post nasal drip! Never had before rny

Anyone had this?  Post nasal drip and sinus congestion.  Last few days it has been pretty consistent to the point I can feel it going down my throat.  This is new for me so I am just wondering has anyone else experienced this?  It has caused me to vomit I know yuck but only thing that is coming up is mucus.  Let me know if this has happen to you and what you did. Thank you kindly!

I had surgery 3 days before you so we are similar in recovery time.   I'm going through the same thing.   I wake up with a stuffed nose,  my nose will start dripping all of a sudden.   Not even when I'm eating.  I am constantly blowing my nose.   It's almost as if I'm allergic to something in the house.   But I know it's not that. 

After surgery there are several different "I am full" signals and one of them is a runny nose... also belching and hiccuping...not necessarily together. I know it is not necessarily what you are talking about... but thought it could be connected.

I developed food allergies after RNY. Eating anything dairy -cheese, yogurt, whey, etc gives me that very symptoms... It sucks. I had to stop eating dairy. 

If you're not sick 37th sinus infection - a trip to allergist may be a good idea.
