The comment about the GP was very real. He was a troubled soul who would, on principal, refuse to believe anything any member of my family said. The point being, seeing that 'spray' of blood vessels was very, very difficult to do, and I wouldn't be surprised if several GPs failed to get the darn things in focus.
What you say about this GP reminds me of a consultation I had with mine of many years ago. In this case it was my eye rather than my ear. At a routine eye test for new specs the optician noticed something he thought should be investigated and gave me a letter for my GP. The GP had a good look at my eye and confessed that he couldn't see anything untoward but he would refer me to a specialist just in case. His reasoning being "your optician spends all day, every day' looking at eyes and if he saw something unusual then it should be checked by a consultant".
I was duly examined by a specialist and the optician was right.
Do you still have the same GP? I hope not!
