Kevin slipped backwards and bangs his head quite hard.
He is able to answer the his friends basic questions quite easily and he stands up. Then someone nearby mentions the possibility of it being a concussion.
‘A concussion?’
‘Yeah, the symptoms include grogginess, headaches, memory loss’
Over the next hour Kevin starts to worry about having a concussion and begins to see signs of each of the symptoms.
It became so bad that Kevin felt he might pass out. Then the doctor told him he had no concussion and all of a sudden all of Kevin’s symptoms cleared up and he was fine again.
Pardon the pun but I believe the symptoms were all in his head.
He was so anxiously on diligent look out for any of the named symptoms that he ended up manifesting them himself. Classic Kevin!
