Learning that there a qualia of "being dizzy" and a qualia of "feeling confused" and learning being able to distinguish those two qualia's isn't easy, if you don't have those qualia in the first place.

Words are cheap once you have the qualia.

Most people have fairly little awareness of what goes on inside their own body. Furthermore these days most doctors also lack the ability to perceive that information kinesthetically but focus on various tests and verbal feedback.

Practically it's also important to think about what information a doctor actually needs. That means who have to know what's normal and how you deviate from that.
