Hi Daisha! The best way to find out what a medical professional does is talk to and shadow as many as you can. For instance, I'm a physician assistant and I've had students like you come in for the day. If you know any doctors, nurses or other medical people, after checking with mom and dad, see if they'll let you hang out in the office. There's a lot of information on the internet but nothing is like seeing it for yourself. If you old enough, you can think about volunteering in a hospital. That's what I did when I was in high school and before graduate school. Good luck!
