Millions of Americans suffer from chronic pain.
Now some doctors are trying brain stimulation to help.
Some suffer from a nerve condition called Anesthesia Dolorosa, which basically feels like the constant stinging of bees.
Some surgeons are now placing stimulation devices into patients' brains, kind of like those used to control shaking in Parkinson's patients.
For one woman, it got rid of terrible pain she'd had for 13 years.
"They were so bad that I would lay in bed and cry. Shake my head and hold my head and scream and cry," said Karen Smith, Patient.
The device can be altered in case the pain returns.
