A healthy 30 year old woman is getting a root canal at the dentist. At the start of the procedure, she notes a metallic taste in her mouth, ringing in her ears, tinglings of her lips, and feels agitated. She is tachycardic, hypertensive, anxious, and feels like she is going to die.
Challenge: What happened?
