Danielle Bradshaw had her right leg removed in 2010 and was fitted with a prosthetic limb, meaning she could enjoy sports for the first time.

The 15-year-old took up sprinting, but says the strain on her left leg causes her constant pain and is slowing her down.

She now wants her left foot - which has deformed toes and severe tendon damage - removed so she can run with two prosthetics.

"We always thought the good leg was good and that was it, but in the last two years it's taken a lot of strain," her stepfather Darren Quigley told the Daily Mail.

"She's taking daily medication, wearing ankle and knee braces and even has a plate under her knee to support her.

"It's all slowing her down.

"Danielle just wants to run and won't let anything hold her back - not even her foot."

The schoolgirl from Manchester runs 100 metres and has won a number of medals at the England Athletic Championships.

She also competes in discus and shot put and has her sights set on Rio 2016.

Quigley added: "Danielle's said to the surgeon that if they won't amputate she'll go elsewhere."

Bradshaw said: "Getting the running blade made everything a lot better.

"I'm not hoping for the operation, I just want to get better like anyone else would want.

"I'll take anything to fix it, though.

"Nothing will stop me doing my sport."
