Desperate Measures/A Stinging Pain - S2.E4

"DESPERATE MEASURES" (a.k.a. "HOME INVASION") After starting a new life in a new apartment, the mother of a little girl notices her child is suffering from a burning rash. At first, doctors attribute it to the eczema she was born with, but it soon turns into a relentless disease that soon threatens her life. The surprising cause of her illness is eventually found to be a simple case of carelessness. "A STINGING PAIN" (a.k.a "DEADLY DENTAL") After a routine visit to the dentist, a man in Arizona comes into the ER racked in unexplained pain. The doctors find an opaque mass in his back. The man's condition deteriorates rapidly, and the doctors must figure out what the mass is before it's too late.
