What I'm describing isn't fantasy; it really happened to me.
It's a long story, but I had terrible wounds on my hand and three broken fingers.
My wife rushed me to the emergency clinic that morning, and I was given a private room.
Unfortunately, the hand surgeon wasn't available until late afternoon. My pain was increasing.
A nurse had already given me some kind of brown powder I had to drink in water to stop the pain. Unfortunately, it wasn't working, and I told the nurse. She said they were going to give me something else.
My dear wife stayed with me in the room the entire time. After about 10 minutes, there was a knock on the door, and I saw a somewhat older nurse in a different color uniform than the regular nurses. She was accompanied by two clearly very young nurses in yet another color uniform. She introduced herself as a teacher from the nursing school and said the two other girls were her students.
She asked (but in a way that left me little choice) if it would be okay if one of her students could give me a morphine injection.
Without much explanation, she removed the covers from my bed and asked me to lie on my stomach. One of the interns pulled my pajamas down completely while the other filled the syringe. And pretty soon after that I felt the needle in my buttock...
Even though I was already a bit dazed from the previous painkillers and the heavy blood loss, I still felt a bit ashamed to lie there like that, while 4 women (the 3 nurses plus my wife) witnessed my discomfort from so close up.
