I have the same problem. My allergies have gotten worse over the years. About 15 years ago I took allergies shots, then 10 years ago I took allergy shots. Now, my allergies are severe and I have been tested and the doc says I don't have allergies. I am fine all winter long, but once spring hits I am miserable. If there is grass, trees and pollen in the air I have trouble breathing (asthma) and I have terrible allergies. I take tons of antihistamines, and nose sprays. Since conventional docs can't help me because "I don't have allergies", I am trying natural ways - eating local honey, taking things to improve my immune system, etc.
How can I NOT have allergies now when I have tested positive 2 -3 times in my life?! My allergies are worse than ever.
I also have had the CT scan done and my sinuses are fine. Ugh!
