I have found that the fear of being unconscious and out of control (of your own safety) is related to the amount of trust you have, in your physician or surgeon.
The more trust, the less fear.
I have been very lucky, in that with only 2 exceptions in my life, I have had a terrific relationship with all of my doctors and surgeons, because I was, literally, trusting them with my life.
If you don’t trust the doctor or surgeon caring for you, then you need to keep looking until you find such a person, who does inspire confidence.
Whatever challenges you are facing, Sir, please know that you have my very best wishes and prayers for your success with “it.”
