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

閱讀難度：

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.

?????? 據(jù)英國(guó)《每日郵報(bào)》報(bào)道，3歲男童奧利弗?杰布森竟然生來(lái)就感覺不到疼痛，他的父母因此不得不給予他更多關(guān)照。

?????? 他曾經(jīng)摔破嘴唇，因?yàn)楹翢o(wú)痛感也不向父母大喊哭鬧。

?????? 奧利弗罹患德朗熱綜合癥，得這種病的幾率是五萬(wàn)分之一。常見癥狀是身材矮小、沒有痛感。

?????? 醫(yī)生當(dāng)初警告稱，奧利弗可能活不過(guò)兩歲。但是他竟然勇敢戰(zhàn)勝病癥、并且取得了令人難以置信的進(jìn)展。

?????? 至今，奧利弗接受過(guò)6次手術(shù)和數(shù)次醫(yī)生會(huì)診。不久前他學(xué)會(huì)走路，能說(shuō)一些簡(jiǎn)單的單詞，大大超出醫(yī)生預(yù)料。
