The 19-year-old, from the Chinese city of Ninghai, developed a fever as a result of the infection.
It started when the teen, identified only by her surname Yang, squeezed a red spot on the tip of her nose, according to Chinese media.
Her right eye became swollen and her temperature soared.
Dr Han Kun, deputy director of the hospital’s department of neurology, told the Ningbo Evening News that the girl was in a critical condition when she was taken to hospital.
He said: “Her life could be in danger if the condition worsens.”
Her temperature reached 102F and the symptoms she displayed were similar to meningitis.
Thankfully she is now in a stable condition, the Daily Mail reports.
She was diagnosed with cavernous sinus thrombosis – which is a blood clot in the cavernous sinuses.
These are the hollow spaces under the brain, found behind each eye socket.
Medics said she became ill after squeezing the spot in what they describe as the “Triangle of Death”.
This, they say, is the most dangerous place a person can squeeze a spot due to the risk of passing an infection through the nose.
