Stubbing your toe hurts so much because you're slamming a tiny surface with a force equal to 2-3 times your bodyweight. Then a bundle of nerve endings called nociceptors fire a danger signal to your brain.

Why does a stubbed toe hurt so much?

Stubbed toes can hurt a lot, even when the injury is not serious. This is because there are many nerves in the toe, including two nerves on either side. There is little fat to cushion the toes, which can intensify the pain and increase the risk of injuries such as bone bruises and fractures.

How long should a stubbed toe hurt for?

Your toe is likely to be tender and swollen, even after a few weeks. You'll likely need to avoid running, playing sports, or walking long distances for one to two months after your injury. Recovery time can be longer if the break is in one of the metatarsals.
