A woman who never felt pain 'enjoyed' experiment which gave her first jolt of it
A 39-year-old woman has felt pain for the first time after an experimental drug trial.
The woman, who has chosen to remain unnamed for security, has never felt pain in her life before the new drug test, administered at the University College London.
John Wood, who helped with the trial and studies sensory neurobiology at UCL, said the woman "quite enjoyed the experiment", which saw her burned with a laser, as reported by New Scientist.
The woman was given naloxone, which blocks the body's natural painkillers, before the laser treatment.
Inability to feel pain is a rare genetic mutation which affects less than a dozen people around the worll.
"It looked like a fantastic drug target," Wood added. "Pharma companies went bananas and made lots of drugs."
