Painful: Arun Rajasingh’s legs have swelled to 5 times normal size and are the size of a baby elephant (Image: Caters)

But despite regularly undertaking physiotherapy and medication to reduce the pain in his legs, no cure has yet been found.

Arun said: “Doctors are still researching my condition and they have not found a cure yet. I get emotional and disheartened sometimes but I haven’t lost hope at all.”

Arun, whose right leg weighs almost 100kg, has been left largely immobile. He uses a wheel chair to get around, and even needs help doing simple daily chores such as getting dressed and going to the toilet.Swelling: the unknown condition has doctors baffled now Arun is seeking help (Image: Caters)

“I have been affected by this condition since my birth. It has affected both my legs, but my right leg is affected really badly,” said Arun.

Despite his disability and his mother’s early death, Arun has gone on to enrol at an engineering college 500 miles away from his home.
