Hi Apples
Best to have it checked out, particularly if there is a painful click. It might be worth seing your medico and getting it examined along with an image.
On the positive, if the area is mildly bruised the muscles may temporarily change their tension (increased guarding) and this can lead joints to click and crack around just due to the recently changed tension - the clicks are then painless. in this case it is nothing to worry about.
However I would always err on the side of caution following a traumatic episode.
