As the past week has shown us with injuries to Enzo Amore and NXT star Kenneth Crawford, a WWE wrestler is never too far away from real-life pain and danger.
Virtually every wrestler on the organisation's roster has suffered some sort of injury during their career, and most would put that feeling down as their worst as a professional wrestler.
According to Chris Jericho, however, it isn't any of the injuries he has suffered down the years that have been the most painful thing to endure during his time in WWE - it is a certain section of the WWE Universe.

Responding to a question on Twitter from a fan asking what the "most physically painful thing" he had endured in WWE was, the veteran Superstar had a rather unorthodox answer:
While Jericho is an expert at winding up fans, and his answer is likely just him in full troll mode, this isn't the first time he has called out some of the WWE Universe.
Whether he is simply taking his in-ring role as a heel to social media in an attempt to get a reaction from fans, or he really is fed up with those fans who tend to spoil things for the rest of the WWE Universe, is unclear.
If we had to guess, it certainly does look like the 45-year-old has grown tired of the minority group of fans.
After almost two decades in the organisation, however, can you really blame him?
It must be tough to take criticism on your job day in and day out and, in the age of social media, it is easier than ever for wrestlers to see exactly how "fans" are reacting to their work.
While the majority of the WWE Universe are clued up and respectful of what goes on in the ring, there are some who seem to go out of their way to act foolishly.
Of course, fans have a right to speak freely on certain matches or feuds, but when, as has been the case recently, fans start throwing things from the crowd or jump into the ring themselves, they can't be labelled anything other than "stupid".
Whether those actions really are as "painful" as a nasty injury is tough to claim, but they certainly seem to be doing enough to grate on one of the WWE's longest serving stars.
