A concussion is a medical condition due to shaking or impact trauma to the brain. Repeated concussions, such as those endured by boxers and professional football players, can lead to permanent brain damage, and thus players of contact sports need to be carefully monitored.
If you are on a sports team, and you or one of your fellow students endures an impact to the head and appears dazed, dizzy, nauseaous, or blacks out, even briefly, you should immediately report the problem to a coach or school nurse, and make sure to tell your parents or see a health care professional as soon as possible.
This is an important question, because it deals with a person's health. To start with a definition of a concussion might be a good idea, since it will give you a sense of the possible seriousness of the injury. A concussion, in short, is some sort of trauma to the brain. Someone could have been struck in the head or even taken a fall that shakes the head. The tricky part to all of this is that a person might look fine, even if there has been trauma to the brain.
Some symptoms include: not remembering what has happened, head aches, feeling slow, balance problems, sleep problems and emotional instability.
In light of the fact that a concussion deals with a person's brain, it is important to see a doctor. In some cases, the injury is minor and only rest is needed. In other cases, the person might be admitted to the hospital for observation. In the end, a person should see a doctor.
You should consult your doctor.
