This happened to me about 2 years ago, typical that it was a BMW M5 convertable
that hit me from behind. I remember being overcome with rage and leaving the SV on its side stand in the middle of the roundabout, storming over to his car and trying to rip him out
. I was pounding my fists on his window and only calmed down when I saw he'd done absolutely no damage to my bike and somehow caused all his bumper and tacky/chav plastic bits to be in bits on the floor. Of course I saw the funny side and after making some comment about money doesn't but brains or a bigger penis I was on my way. B*****d SMIDSY
Anyway, my point was if you think it'll help your confidence get it checked out by all means, but if it still feels the same and there's no obvious damage I'd save the money and not take it in.
