Five months later, I still felt weak and had terrible muscle aches. I went to a doctor. By the help of an MRI-machine, the doctor found the cause of my problem.MRI means magnetic resonance imaging. An MRI machine takes pictures and shows them on a computer. It uses radio waves to see inside the body.
