A Chinese doctor shared a video of the unusual cause of a patient's ear discomfort -- a spider building a nest inside his head.

The video filmed at a hospital in Yangzhou, Jiangsu province, shows the inside of an ear belonging to a patient identified by the surname Li.

Li came into the hospital complaining of discomfort in his ear and the doctor looked inside to discover a small spider was building a nest inside the man's ear canal.

The doctor said the spider was too small and fast to be grabbed using tools, but hospital staff were able to use water to flush the arachnid out of the patient's ear.
