Brave little boy: Oliver Jebson (right) who cannot feel pain with his parents Hayley, 25, and Dean, 27, and brother Lewis.

阅读难度：

Three-year-old Oliver Jebson doesn't notice when he has hurt himself, the Daily Mail reports. His parents have to watch him extra carefully because he is not able to feel physical pain.

He has even split his lip open before without shouting out to his parents.

Oliver was diagnosed with Cornelia de Lange Syndrome, which affects just one in 50,000 children, at birth. The condition causes sufferers to have stunted growth and occasionally can mean that pain sensors are blocked out.

Doctors warned Oliver's parents that he was unlikely to survive beyond his second birthday, but Oliver has beaten the odds and is now making incredible progress.

After six operations and dozens of hospital appointments, Oliver has recently taken his first steps and has uttered his first words – years ahead of schedule.

英3岁男童天生无痛感

       据英国《每日邮报》报道，3岁男童奥利弗•杰布森竟然生来就感觉不到疼痛，他的父母因此不得不给予他更多关照。

       他曾经摔破嘴唇，因为毫无痛感也不向父母大喊哭闹。

       奥利弗罹患德朗热综合症，得这种病的几率是五万分之一。常见症状是身材矮小、没有痛感。

       医生当初警告称，奥利弗可能活不过两岁。但是他竟然勇敢战胜病症、并且取得了令人难以置信的进展。

       至今，奥利弗接受过6次手术和数次医生会诊。不久前他学会走路，能说一些简单的单词，大大超出医生预料。
