Well if you want an simple example, here's one:
Hola Doctor, acabo de estar en un accidente de auto. Tengo un severo dolor de cabeza, mi abdomen está hinchado, y tengo un moreton en la espalda.
You basically have to imagine injuries that might have happened to you if you got into a car crash. Like ¨tengo una cortada en la frente¨ or something along those lines.
