Me: "My nose has been clogged since the 90s, I'm on three different antihistamine prescriptions, do you think surgery might help me?"
ENT: "Surgery? I mean, it might help a little. Might make things worse. What I'd really recommend is figuring out what you're allergic to. Let me write you a referral to an allergist instead."
Me, confused: "Wait, I'm allergic to something?"
ENT, more confused: "You didn't realise? Did nobody tell you you've displaying obvious symptoms? Why did you think you were on the antihistamines?"
Me: "Uh...."
So yes. I'd certainly recommend checking allergies, but the good news is, some ENTs are sensible. (Then again, this was the NZ medical system, which probably matters...)
