A 37-year-old Chinese man, who suffered from chronic migraines, finally has some relief after doctors removed a 4-inch knife blade that has been in his head for more than four years, AsiaOne.com reported.

Li Fu, from Yunnan Province, was stabbed in the head during an armed robbery in 2006, but doctors who treated his injuries at the time did not realize the knife was embedded in his skull.

Last month, doctors finally took an X-ray of Li’s skull, to find the source of his headaches, and that’s when they made the startling discovery.

Li underwent surgery on Sunday and is now in stable condition.

Surgeons at People's Hospital of Yuxi said it was a miracle that he had survived with that type of injury for so many years.
