1960s

Jo Cameron only realised in her sixties that it was not the norm to never feel pain. It wasn’t until she came out of a notoriously painful operation unfazed that her doctor suspected Cameron was different. She has gone through life bumping into things, burning herself and even getting her teeth knocked out without feeling any pain. Scientists at University College London hope that research into the mutated genes which cause Cameron’s condition will lead to better treatments for chronic pain, PTSD and wound healing.
