A MAN plagued by headaches discovered a SIX-INCH long worm had burrowed into his brain.

Wang Ming, 60, from Chengdu, China, visited his doctor after he had suffered fainting fits and painful migraines for more than six months.When they X-rayed him, medics spotted a parasite the length of a biro lurking under his skull.

Surgeons performed a three-hour operation on Ming at the First People’s Hospital in Shuangliu earlier this month.

When they removed the worm, they put it in a water container and were shocked to discover it carried on swimming.

Experts, who believe Ming picked up the parasite from eating undercooked food, now plan to study the worm.
