Jo Cameron only realizes that her skin burns when she smells scorched meat. She often burns her arms in the oven, but feels pain free to warn her.
That's because she's one of only two people in the world known to have a rare genetic mutation.
This means that she has virtually no pain and never feels anxious or anxious.
It was not until she was 65 that she realized she was different ̵
When she operated on the hand, the doctors warned her that she should reckon afterwards with pain.
When she did not feel anything, her anesthetist – Dr. Devjit Srivastava – she's a Pain Painter at University College London (UCL) and Oxford University.
After testing, they found gene mutations, which meant she did not feel pain like most people did.
Not Just "Unbelievably Healthy"
Jo told BBC Scotland News that the doctors did not believe her when she said she did not need pain relief after surgery.
She said, "We had fun in front of the theater when I guaranteed that I did not need painkillers."
"When he found out that I did not have one, he checked my medical history and found that I never needed analgesics had asked.
It was subsequently referred to professionals in England.
After the diagnosis, Jo realized that she was not just "incredibly healthy," as she had believed.
She said, "Looking back, I realize that I did not need painkillers, but if you do not need them, do not question why you are not."
"You are what you are until you are someone points out that you are not questioning it .I was just a happy soul who did not know that anything was different about me."
You did not even have pain during the birth and remembered, "It was just weird, but I was in no pain. It was really enjoyable."
Jo makes the Scotch Bonnet Chili Challenge
Her husband Jim and her anesthetist dr. Devjit Srivastava, Jo, participated in a chili challenge.
While the two men are reacting to the heat of the chili, Jo continues to smile – unimpressed by the spice.
Jo would not change anything, but thinks pain is important and says, "Pain is there for a reason, he is warning you – you hear alarm bells."
"It would be nice to have a warning, if anything not true – I did not know that my hip was gone until she was really gone. I could not go with my arthritis. "
The Lucky Gene
Doctors believe that she may also be able to heal faster than normal.This particular combination of genes also makes her forgetful and less anxious.
" One calls it's the lucky gene or the forgetful gene. I annoyed people because I was happy and forgetful all my life – I have an excuse now, "she said.
Jo recently said she had a" slight bump "in the car but was unaffected by what many felt distracting.
"I do not have adrenaline. You should have this warning, it's part of being human, but I would not change it. "
The other driver, she said," was shaking as usual, "but she could stay calm." I do not get this reaction .. "It's not brave, the fear just does not happen."
Could Jos Gene be the key to helping others?
The researchers say it's possible that there are more people Jo.
" One out of every two patients still has moderate to severe pain after the operation today, despite all the advances in painkillers. It remains to be seen whether new treatments could be developed based on our findings, "said Dr. Srivastava, 19659007]" The results indicate a novel analgesic discovery that may provide postoperative pain relief and also accelerate wound healing. We hope this can help 330 million patients undergoing surgery worldwide each year. "

The case of Jo is the subject of an article published in the British Journal of Anesthesia by Dr. Srivastava and Dr. James Cox of UCL.
Dr. Cox said, "People with infrequent pain insensitivity can be valuable to medical research because we learn how their genetic mutations affect the sensation of pain. Therefore, we would encourage anyone who has no pain.
"We hope that our results will eventually contribute to clinical research in terms of postoperative pain and anxiety and possibly chronic pain, PTSD and wound healing."
