Absolutely terrible writing and acting in the episode about chronic insensitivity to pain. They had the actor act like they didn't feel good, shivering, cold, acting like they're stomach hurt, looking like they were in pain.. Maybe the writers, actors, directors don't understand what it means when someone doesn't feel pain! Do better! Incredibly short sighted. And, just so know the Dr. Isn't going to believe that they have it without convincing.
