Very interesting. I think observation and diagnosis lacks in so many doctors today. My dad was a great diagnostician he is long gone but was a urologist and surgeon. I remember talk at the fing table about patients of his. As an adult I’ve been subjected to as wide range of doctors in general practice or internist I’ve had two good ones. My current doctor however just dumped me or I chose not to pay her concierge $$ as I’m very healthy and have limited retirement income. Now I’m on the search for one like you with acute observation skills and can diagnose properly! Good for grandmother teaching u these skills. Oh that more had grandmother’s like yours.
