Best advise: "Don't google".

I think googling is good for people who don't go to the doctor because they decide their symptoms aren't serious.

Sounds like you and your granddaughter are having fun :) I'm glad she's well.

I had a mysterious illness that I ended up self-diagnosing. See http://camoo.freeshell.org/allergies.html
By googling and looking on Medline, I found there's a lot of evidence for local allergies, i.e. you can have an allergy to something even though allergy tests are negative. This could happen because the allergy is local to a particular organ, like the nose - or perhaps an excess no. of mast cells takes up all the IgE in the blood.
It seems the allergists I saw weren't keeping up with the research. A common problem with doctors it seems. States in the United States require about 12-50 hours of continuing medical education per year ... that cannot even HOPE to keep up with medical research. No requirement for a set # of CME hours in my state.
I don't know that I have what researchers call local allergies, it might be some non-IgE mechanism. It wasn't just googling, I did a lot of personal experiments to find out what was going on.
Doing one's own research might be especially relevant with allergy problems, since the immune system seems to be very complicated and not very well understood, and people can observe their own reactions to the environment.
