Unfelt Pain: Medical Mysteries and Miracle - - Eight-year-old Gabby Gingras Suffering From HSAN Type V

Life Full of Danger for Little Girl, Gabby Gingras, Who Can't Feel Pain

As much as it hurts, pain teaches us important lessons (not to touch a hot stove, for example). People with a rare genetic disorder known as hereditary sensory autonomic neuropathy (HSAN) type V feel no pain, however, and may never learn those lessons.

Eight-year-old Gabby Gingras constantly and unwittingly injures herself, sometimes seriously. She has knocked out all but one of her adult teeth (which grew in early after doctors suggested pulling her baby teeth), and as a baby she scratched herself blind in her left eye. She now wears safety glasses and sleeps in swim goggles to protect her right eye. There is no cure for HSAN type V, but as people age and learn how to manage their condition, they can lead relatively normal lives.
