<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am extremely jumpy. Anything will startle me. A person could walk up behind me and greet me in a normal tone of voice. A person could put a hand on my arm to get my attention. Someone could accidentally drop something like a book... All will set me off. I will be jumping all over the place. Of course, my friends like to startle me on purpose and they think it is the funniest thing.
