Talk to Ent Specialist on Nose Issue

When I talk to someone continuously, like 1 hour. After that I feel some kind of itching internal in my nose. Moreover, I feel that when I breathe in, the air is going directly in my brain.

I feel better after 30,40 minutes of break (not speaking)

I don't know how to describe it, but I hope this makes sense.

Please tell me what kind of issue is this? And its remedy?

Thank you all in advance!
