My Evil Twin is Driving Me Crazy (S07E06)

Title: My Malevolent Doppelgänger is Making Life Difficult Plot: A young boy in Pennsylvania, just four years old, experiences a runny nose with a reddish discharge, severe stomach aches, pale complexion, and intense pain after accidentally inserting a button battery into his nostril. Meanwhile, an Idaho college student suffers a knee cut that escalates into excruciating leg pain and ultimately leads to septic shock due to an Aeromonas hydrophila infection. In another case, a woman from Pennsylvania exhibits bizarre behavior and mental confusion caused by a teratoma on her ovary, resulting in Anti-NMDA receptor encephalitis.
