A once-active teen has been left wheelchair-bound after spontaneously developing a painful condition dubbed "suicide disease".

Izzy Clements, 14, had just started in year eight when she found herself experiencing headaches and sickness - which grew so severe she lost 10kg in two weeks.

Doctors couldn't work out what was wrong for months - then Izzy, a once-keen gymnast, dancer and horse rider, grew weaker and began suffering with leg pain.

The teen, from Leicester, had to drop out of school and ended up in a wheelchair due to the constant pain that was so severe it would even cause panic attacks.

Eventually doctors questioned if she had complex regional pain syndrome (CRPS) - dubbed the "suicide disease" as the pain has previously driven patients to attempt to take their own lives.
