Danny (is that how you spell it?),
This is an interesting narrative that presents your own subjective experience of the drugs, surgery and other phenomena related to your knee injury. What’s missing is a bit more detail on the events outside of your mind that actually happened. What’s going on in your mind is VERY interesting, and I’m glad it’s in your current draft. But we need also to show the reader what happened to you in the “outside world” so that they can have an even clearer sense of how your “interior world” was responding to this experience. With that in mind, I’ve made several notes above about where you could expand on the details relating to certain important events in your story.
