Allergy Mystery - should I get a second opinion? What allergy do I have and should I get a second opinion?
I started having allergy symptoms several years ago.  I tried Tylenol Allergy and it helped. So 2 years ago I went in for an allergy test and the results showed that I was allergic to pet dendar and dust.  I was perscribed allegra-d and was OK taking it.  For 2 years I have been taking allegra-d and tylenol allergy complete as needed. 
This March I started having the these symptoms: runny nose, congestion, itchy/wattery eyes, sneezing, dry cough, itchy skin, midnight sneezing attacks. I again took my allegra-d and it helped. I was curious why It got worse and if it could be seasonal, so I scheduled an allergy test again, and I also tried 1 session on accupuncture for my allergy Friday. So it has been 4 days since the treatment. 
Today the test showed that I am allergic to NOTHING!
The doc said that it's polution related and I should have a tube down my nose test to check if something else causing  irritation. How can he be right
