afraid of carpal tunnel sydrome

I remember the time when I was chatting with my online buddy thru yahoo messenger. She told me that she’s watching videos on youtube which is about surgery. She let me see a video about the carpal tunnel syndrome surgery. While I was watching it, all of a sudden I felt weakness and nauseous. I know I shouldn’t be feeling like that because when I was still a nursing student and nurse trainee I was used to seeing blood at all. Well, maybe the reason why I had a sudden feeling of weakness when I saw the video, it’s because I’m kinda afraid of having that kind of health condition. Well, I really wish not to have carpal tunnel syndrome.
