Marion Yau – aka Miss Foot Fixer – undertook the gruesome procedure at London’s Harley Street Foot and Nail Clinic in December.
The recently-released footage shows her cutting away the skin in order to reach a yellowed nail lodged into her patient’s toe.
But as soon as the incision is made, pus starts squirting out.
Marion had to eventually clean the yellowy liquid away to then extract the nail.
It left the man with a gaping hole on his big toe, which was bandaged up to prevent infection.
She said: “This is a very bad case of ingrown toenail as the piece of nail left inside his toe was very big.
“Usually the ingrown toenails are not as big and the infection does not leave such a big hole in the foot.
“The wound was cleaned and dressed is applied, I also recommend the patient wears wider shoes to prevent the nail from digging in.”
The NHS has previously given guidelines on how to treat ingrown toenails at home.
They recommend soaking your foot in warm water three to four times a day.
It comes after a cyst was popped on a man’s tear duct – causing pus to erupt from his eye.
And a river of infected pus was unleashed after two pea-sized cysts were prodded.
