Doctors don't know why my legs are getting bigger: Doctors can’t tell Mandy Sellars why her legs keep expanding – all they say is that her only option is a drastic amputation. She travelled to the US for a new TV show in search of an alternative...It’s not easy being Mandy Sellars. She has hugely outsized legs that make having a normal life nearly impossible. People stare whenever she leaves the house, she needs a special car to get around and can’t work full time. What’s more, her condition is getting worse and doctors say she needs an amputation so severe she won’t be able to sit up. And she doesn’t even know what’s caused it.
