When I was self diagnosing, my Google queries were simplistic.

E.g.

resistant hypertension many medications

Which led me to a couple of research articles about pheochromocytomas and a Washington Post article about someone with high blood pressure on a "bucketload of medications".

e.g. https://www.washingtonpost.com/health/2022/04/23/high-blood-...

If the LLM can provide a sample Google-like analysis, data points that my 7 specialty doctors missed, that's an improvement.
