Inside Strictly star’s agonising health battle
ROBIN Windsor was forced to quit Strictly or "risk ending up in a wheelchair", it has emerged.
The 44-year-old BBC star previously opened up about his exit from the show, before his tragic death.
Robin left Strictly in 2014, claiming bosses had axed him following a "horrible back operation".
Speaking at the time, he said: "Leaving Strictly wasn’t my choice.
"I had a horrible back operation and they decided that they didn’t want to ask me back the next year.
"It was probably for health and safety reasons, in case something happened, but I was physically fit."
Talking about when the horror injury happened, Robin explained he had "slipped a disc in [his] back", adding that "the nerve was exposed, causing agonising pains shooting down [his] leg".
He said: “I was paralysed on the floor of my friend's house as the pain was so bad. I was there for three or four days.
“I couldn't risk going ahead. It was a heartbreaking decision but I had no choice.
"If the slipped disc had popped out while I was dancing, I could have ended up with permanent nerve damage and been in a wheelchair.”
"He sounded absolutely traumatised – whatever had happened must have been truly awful."
Weeks later he shared a quote from Dr Thema Bryant hinting that he had experienced trauma.
It read: "Trauma teaches you to expect and accept the bare minimum.
"In this new season, may you adjust your standards and learn to receive the maximum.
"You are worthy. You are enough. You deserve overflow."
His final Instagram was a black and white mirror selfie captioned: “Hiding in the shadows.”
The dancer had spent his final days working on a luxury cruise ship and taking in the sights of Africa.
