Im not saying I have reflux, Im saying thats my theory
Ive never had a reflux diagnosis. I just know I have an ulcer

H.Pylori bacteria causes a great many gastric ulcers.  This bacteria is
a relatively slow growing bacteria.  An ulcer infection also is like
any other infection in that it lowers your bodys immune system response
to other attacks (i.e. sinus bacteria or viruses).  Like any bacteria
this bacteria may also be able to infect the tissues of the throat and
sinuses.

Not being a Doctor, but having one in the family, I am well aware from
personal experience how any immune system inflammatory response can
aggravate other less problematic areas.  For example, if my
immunosupressive therapy injection (allergy shot) increase is too
great, my joints swell up and hurt as they will be inflamed, along with
an increase in congestion and sinus drainage.  Same goes for the flu
shot, which illicits an immune system response and minor inflamatory
reaction.  This is why (as I was told) during the pollen allergy season
I am prone to have acne breakouts from a staph bacteria, one time was
very serious requiring surgery to remove the infected tissue.

I did alot of cooking yesterday (carmel corn ice cream, chocolate stout
milkshake, homemade coconut milk virgin pina coladas and beannaise)
I ATE a LOT!!!
I woke up with a stuffy nose!
HHHHHMMMMM!!!
