Hi Miss Michelle,
The symptoms you have mentioned suggests towards Concussion injury
. Following symptoms can be seen:-
> Loss of memory
> Irritability or confusion
> Persistent headache
> Episode of unconscioussness
> Episode of seizures
> Difficulty in balancing the body
It takes few days to weeks to heal properly with complete rest. Rest should be both physical and cognitive i.e. no television and no messaging etc. during rest period.
It is advisable that you should have a scan of your head done and get yourself examined by Neurophysican first.
Hope I am able to help you.
