Being a medical student I can understand your feelings and the purpose of your writing.
Our teachers have always focused more on the physical examinations and have taught us to make your diagnosis on the basis of examination and never order unnecessary tests, it just indicates your incompetentness and wastes patients money. At the same time we can't be thankful enough to science and technology, as it has made the process of diagnosis very easy and efficient.

And I personally believe that the relation of empathy between patient and doctor is as necessary as medicines😊
