Having acid reflux is a sign that your/our body is too acidic and reflux is our body intelligence trying to get rid of all that acid. Just something to think about.
Having acid reach your nose isnt uncommon in reflux sufferers. I've felt it in my back, throat and just the right side of my chest. It can manifest differently for each person. Are you on any medication for reflux? Are you eating more fruits and veggies? Are you still drinking coffee, pop, alcohol, etc.? Do you smoke? Diet modification is key in dealing with this condition.
I would suggest you take some type of antacid before you retire to bed. My doc told me to take 2 spoonfuls of maalox after each meal and before bed, in addition to dexilant in the morning.
You could also try a natural approach and drink 2-3 cups of ginger tea throughout the day, it helps with digestion issues. That worked for me but made me lose weight (ginger does that) so I slowed my intake of the tea.
Hope this helps!
