Allergy related?

Just wondering if my recent confirmation of maple, oak tree, and Bermuda grass can be the cause of my GPN? I am a teacher and often have debilitating pain as I prepare to return to work in September. I have been struggling with GPN for 7 years. Seems a pattern in the time episodes trigger. Anyone else able to connect the dots to environmental allergens? My doctors don’t know enough about GPN on Long Island, NY to agree/disagree with my theory.
