One thing a lot of people don''t seem to be aware of is that injuries can often times show up significantly delayed. A concussion from a head injury can sometimes only start showing symptoms after a week.


    There are also cases where these injuries continuously worsen over a period of multiple weeks before the person realizes the original cause of said injury.


    If you''re in a country with "free" healthcare, just go for a checkup since you''re already paying for it.
