I did a for more searches and it looks like home made root beer contains Yeast, too. Hmmmmmm ?
Wonder if Yeast is your allergy? Please let us know what your doctor says.

Not being a doctor, I can't say but am wondering if you have a Yeast allergy. Yeast is found in the pizza dough and also in alcohol.
Do you have a nut allergy? Some rums contain nuts, some beer can contain nuts, too, from what I've read online.
Having asthma-like symptoms can be the beginning of anaphylaxis. Please be careful and see an allergist or doctor. Not sure about the pain you get behind your ear
Histamine, Yeasts (which explains the pizza crust & alcholol), Sulphites or Sulphur Dioxide or Additives are all things to explore with an allergist, too.
Please keep us posted!

I am no doctor, but I have the same issue...it is a ripping, bubbling, burning sensation. i believe mine is related to my TMJ.
