I'm sorry to hear of your health problems, but unfortunately doctors don't have tricorders yet. It's quite incorrect to suggest that people with "zero intellectual curiosity" are sought out by medical schools, in fact it's a preposterous claim.

We have made great advances in medicine in the past 100 years, but complete understanding of the human organism and its diseases still lies far in the future. Some diseases have no "tests" or definitive diagnostics; they are identified by ruling out other possible causes of the symptoms. This can take time.
