A 28 year old man from Southport UK almost died after tearing his skin while biting off a fingernail.

"I bit the nail and it pulled down the side of my nail and got infected," Luke Hanoman, 28, told BuzzFeed News.

Afterwards, he started getting chills, cold sweats and fever among other flu-like symptoms.

His finger swelled and started throbbing and he had trouble focusing.

Hanoman thought he just needed rest but ended up sleeping until late the following afternoon. His mother got worried about him, after recognising the symptoms.

After calling the National Health Service hot line, they were instructed to go to hospital immediately.

Hanoman ended up staying at the hospital for four days on intravenous antibiotics due to sepsis.

Anyone can get sepsis from any infection.

The most common infection sources for sepsis are pneumonia, urinary tract infections and skin infections.
