Mystery ER Season 1

Doctors are puzzled as they examine little Ricky, a frequent patient of the E.R. with persistent vomiting and an odd rash around his mouth and chest. There's no explanation for why the young child wheezes, but his every breath is a painful struggle.

When Aaron's panic-stricken parents bring their son into the E.R. with seizures, doctors discover a strange mass inside the boy's brain. Fearful it's cancer, they prepare Aaron for a biopsy until a sharp-eyed radiologist identifies it as a pork tapeworm.

Arunas has lived his life in good health, but after turning 50 he suddenly experiences recurrent bouts of vomiting, heart palpitations, weakness, and malaise. After rigorous testing, doctors suspect he is mentally ill, but one last test says otherwise.

The pain in Alice's legs and back is unbearable. Doctors find nothing and suspect she's neurotic. When her son and neighbors begin to experience similar symptoms, the doctors are baffled. But the cause is not an epidemic, it's a vindictive boyfriend.
