A man who cracked his own neck to avoid chiropractor bills ended up losing his vision.

Andy Wilson, 53, from New South Wales, Australia, suffered from a bad back since he was a child and sought help from a variety of chiropractors but found continuing treatment as an adult too expensive.

His attempt to save money led to life-threatening consequences when he tried to mimic the experts’ movements and do his own neck adjustments at least twice a day.
