You're in the clinic and about to walk into a room to see a patient with a non-specific chief complaint like dizziness. In your head, you know the dizziness could mean something benign and self-limiting or emergent and life-threatening. You know you learned about the HINTS exam in your training, but now you're questioning if a positive head impulse is good or bad. You're starting to think, "Gosh, do I know anything? Why did these people hire me?" If you relate to this, you may have experienced imposter syndrome.
