It is important for someone who may have a concussion to be checked by a health care professional. Concussions are not usually life threatening, but someone with any of the following symptoms should be taken to the emergency room:
- Loss of consciousness, even briefly, or severe drowsiness.
- A headache that worsens even with rest.
- Repeated vomiting.
- Decreased or irregular breathing.
- One pupil larger than the other.
- Increased confusion, agitation or restlessness.
- Weakness, numbness, tingling, or decreased coordination.
Athletes believed to have a concussion should be removed from play and not allowed to return until evaluated by a health care professional who can clear them to play.
