Concussion | Complications


What are the risks of returning to play too soon?

If you return to play before completely recovering from a concussion,  a second blow to the head—even a minor one—can be dangerous. You are at risk of a rare condition called second impact syndrome. This is a rapid brain swelling that is usually fatal. Never return to a sport or recreational activity after a concussion until you have been cleared by a doctor.
