Pain is something that the vast majority of us just have to deal with, and sometimes on a daily basis. Not being able to feel pain is almost unimaginable, but that’s the life one woman in Scotland has been living for 66 years. She doesn’t feel cuts, burns, and even surgery doesn’t register with her, and she’s lived her entire life thinking that was perfectly normal.

Her case, which was published in the British Journal of Anaesthesia, only caught the attention of doctors after she recovered from orthopedic hand surgery with no reported pain. As with all patients, she was given a suite of pain-numbing meds while the operation was carried out, but even after the drugs wore off she reported absolutely no pain whatsoever. That’s when doctors realized something was amiss.
