After suffering a recent concussion i realised how little i know about such a common and potentially threatening injury.
A concussion is a mild form of traumatic brain injury (tbi) caused by a bump, blow or jolt to the head. It can also be caused by a violent movement or jarring of the head or neck. Generally a mild concussion recovers fully quite quickly however in more severe cases can last for weeks or even days, for about 9 in 10 people with concussions the symptoms will disappear entirely within 7 to 10 days. Once you’ve had a concussion you then become more susceptible to suffering further ones which can be problematic in a number of contact sports, which are the most common cause of concussion (the average speed of a football hitting a head is a massive 70mph more than three times the strength of a boxers punch).
Immediate can include headache nausea vomiting blurred vision fatigue or unconsciousness although this is not always the case. The danger of concussion is now being given more importance although still a high percentage of athletes (around 25%) fail to get assessed by medical personnel.
As you can see in the video, getting hit does not tickle!
