Like being an NFL lineman at the end of a long season. You play in pain from multiple nagging injuries that just won’t heal until the off-season... except there really isn’t am off season.
There is no off season in wrasslin... I believe they generally working 3-4 nights a week 50+ weeks a year. Once you are injured, you never really get time to heal... at least not the day to day type of injuries.. obviously serious injuries are a different story...
I doubt a top tier working wrassler is ever working without an injury
