Canadian soccer player Ismaël Koné used a small green device after an injury. Fans wondered what it was.

The device is called Penthrox. It's a fast-acting pain medication that you use yourself.

A doctor said the patient must hold the device. If they can't, the drug can't be used.

The doctor likes Penthrox because you can't take too much. You can stop using it if you feel better.

The pain relief starts after a few breaths and can last about an hour.

Penthrox is like laughing gas. It helps with pain and makes you feel better without knocking you out.

Penthrox was first made in the US in the 1960s. It's approved in Canada, Australia, and New Zealand.

In Australia and New Zealand, people use Penthrox for accidents and injuries.

The US doesn't approve Penthrox anymore. It's not safe for people with liver or kidney problems.

Koné had surgery for his broken leg. He won't play in the tournament anymore.
