Jot, I'm really glad to hear that everything turned out okay. What a lot of unneeded stress!
Writing about personal medical experiences is a very common theme for essays. It can be effective, but it needs to be very personal and reveal something more about your personality. Dig a little deeper and try to figure out exactly what interested you -- what parts of your own personality identified with the medical personnel you saw, for instance. Otherwise it's going to be like so many other essays with the same theme.
I have to say that I've never seen anyone write about a horrible medical experience (like Jot's, for instance), but if done right I bet it could really stand out! Maybe how a malpractice suit inspired your career ambitions?
