The athlete went on to say that, despite having found a third of the needle, she did not initially assume the remaining two thirds were lodged in her foot.
"It didn’t seem to hurt too much so I put my shoes and socks on, shepherded my two young children out of the hotel, into our transfer, out of our transfer, entertained them for the three hour journey to Cairns, traveled from Cairns to Port Douglas, did two loads of washing, went to bed, got up at 5:30am to go the gym, went to the gym, took the boys to gymnastics."
But at 12pm the following day, Turia could no longer ignore the pain that had been building since the incident and was now "unbearable".
After her partner, Michael Hoskin, arrived home from work, he drove the 34-year-old to the nearest hospital.
"I was half expecting them to say 'You silly sausage, it’s just a bruise'," the motivational speaker wrote. "But instead they said, 'Wow, it’s really deep'."
Not only was the needle still in Turia's foot, it was resting on a nerve amongst her bones to the point where the athlete required surgery.
"I had an operation to remove the needle and woke up feeling like my foot was on fire," Turia added on her blog. "But each hour that passed after that, I got better and better. I needed less pain medication because I was getting better, my head fog cleared, I was no longer thinking about the pain."
