Prax Sanchez of Colorado coughed up a nail that was stuck in his nose for three decades. It came out after he underwent a medical MRI. Of course, MRIs are essentially giant magnets which is why you have to remove any metal objects before entering the machine. From KKTV:
"When I went to lay down on the MRI machine, I had a real pain on my right side under my eye," said Sanchez..."Man Coughs Up Nail Stuck In His Nose For 30 Years"
It was over an inch long. Doctors say it could have been up his nose for 30 years.
"Once it's in the nasal cavity like that, a little membrane forms around it and it becomes a foreign object."
