If you fully accept everything BobaFloutist says, what do you do differently?

Nothing. You just... feel more sympathetic to doctors and less confident that your own experience meant anything.

Notice what's absent: any engagement with whether the AI-assisted approach actually worked, whether there's a systemic issue with ENTs not being current on allergy research, whether patients should try OTC interventions as cheap experiments, whether the 25% localized-reaction finding is real and undertaught.

The actual medical question and its resolution get zero attention.

Also though...

You are sort of just telling people "sometimes stuff is going to not work out, oh also there's this thing that can help, and you probably shouldn't use it?"

What is the action you would like people to take after reading your comment? Not use ChatGPT to attempt to solve things they have had issues solving with their human doctors?
