Runny nose was leaking brain
An Arizona man who thought he had a chronic runny nose was told by doctors he actually had a leaking brain.
Joe Nagy initially noticed a clear liquid dribbling out of his nose "like tears out of your eyes" once or twice a week, reports the Daily Telegraph.
But it soon became a problem week round and failed to clear up, despite him taking allergy medicine.
After 18 months, he eventually sought the opinion of a specialist after an embarrassing incident in which a dollop splashed on to blueprints for model aeroplanes.
Doctors found that the membrane surrounding Mr Nagy's brain had a hole in it and his brain fluid was leaking out.
Peter Nakaji, a neurosurgeon at Barrow Neurological Institute, said the brain produces up to 12 ounces of brain fluid a day.
"You don't really think about it, but our brains are really just above our noses all of the time," he said.
Dr Nakaji was able to find the leak and was able to fix it with routine surgery and Mr Nagy is now recovering.
