For 21 long years, Don experienced so much agony and stiffness, he thought he'd never know what it would be like to be pain-free again.
A former police officer, Don was forced to retire early and go on ACC when his pain began interfering with his job.
He sought help everywhere he could, trying, as he puts it, "every product worldwide."
Nothing worked. Instead, the pain and stiffness just kept getting worse.
Don said, "I had all but given up hope. Retirement had just become a never ending waiting room for me."
