So I've been battling a little sinus thing / allergies for the past month and today it seems I am having horrible post nasal drip. Every time I swallow I feel it going down my throat and I think its starting to effect my stomach. It keeps making noises, is very gassy, and just aches if I move a certain way. I do not feel n* at all. I was able to eat a bunch of food throughout the day. However, whenever the drip starts up again it aches and earlier today I was having some acid reflex coming up in class...my throat kept making crazy noises. Is this normal for nasal drip? Does it effect the belly? I took a Claratin D ..hopefully this clears it up!
