So a woman is claiming that a hickey caused her left arm to be paralyzed.

“Because of the physical trauma it had made a bit of bruising inside the vessel,” said Wu. “There was a clot in the artery underneath where the hickey was.” The clot had gone into the woman’s heart and caused a minor stroke that led to the loss of movement, he said.

Holy hell! You can have a stroke because of a hickey!
