It took just 15 minutes for Ian McDonald's sore shoulder to turn into pain so excruciating it felt like a knife cutting into his spine, and he is unsure what type of injuries he would have now if he had not been airlifted to hospital.
The 26-year-old fell off his quad bike after a charity ride at Kawakawa Bay last month, and despite being able to push the bike off himself and ride it to a nearby ambulance, his condition deteriorated quickly.
"Originally I just had a sore shoulder, but at the beginning of the ride they told us that any accident had to be reported so I was doing that," he said.
"Then I just remember that the pain was unbelievable, basically like someone was trying to cut me open with a sharp knife from my neck right down my spine."
Mr McDonald said he was unsure what would have happened if the Westpac Rescue Helicopter was unable to airlift him to Middlemore Hospital in time, and encouraged people to get behind the organisation during its appeal week starting today.
