Shaughna Phillips had blood pouring down her leg during 'The Real Full Monty On Ice' rehearsals and was in "so much pain".
The 'Love Island' star recently underwent surgery on her calves after being diagnosed with lipoedema - an abnormal build-up of fat cells - and found herself in agony months later while she was preparing for the upcoming ITV charity show.
She told The Sun Online: "The first day of training I couldn't get my foot into my boot. There was blood pouring down my laces. I was in so much pain."
The ITV show will see a group of celebrities take their kit off while dancing on ice to help raise awareness of testicular and breast cancer.
Shaughna joined the show in honour of her late father, Eddie - who died in 2016 after an 18-month battle with cancer - and she refused to quit the show despite her pain.
She added: "I was skating in my dad's memory so there was no way I wasn't going to do it. Plus I'm an Aries, it's not in our blood to quit."
The 26-year-old beauty underwent the procedure after a fan asked if she had been diagnosed with lipoedema, but Shaughna didn't know it was a medical condition.
She explained: "It was a huge relief getting diagnosed. I just thought I had a big problem area but to know it was a medical condition was a huge weight lifted from my shoulders.
"Half the battle was won as soon as I was diagnosed. I thought I had really bad water retention. I was taking lots of water tablets and had so many near misses when I was in the car."
However, she may have to undergo the surgery again later in life as the condition can flare up during pregnancy.
She said: "Hopefully I won't have to have the procedure again, but the condition can flare up again with pregnancy so, if that happens, I'll have more surgery. "
