you go to a doctor - having a medical issue. One possibility is to just go along, make a small adjustment to diet, add a little supplement. See if it gets better.
But your family doctor sends you for a second opinion to a guy at a big teaching hospital. He says they have a procedure that will reroute your nerves and a couple of blood vessels, but you will feel much better in the long term. You sign up for the treatment. Phase one is temporary. There are some issues, but the doc at the teaching hospital adjusts it some. Then you go in for the second, permanent phase of the treatment. The doctor come into your room, discusses what he's doing, you have some doubts, but he says trust me, we'll keep an eye on it and adjust as needed, This complex procedure will be better inthe long term, You go ahead
After surgery, you come to the recovery room and ask when the doctor will come around on rounds. The nurse tells you he has left the hospital. You say, yeah, he must be tired. She says, no he has left and isnt coming back.
You say, WTF
