I’ve also had many cases over the years where what seemed like a minor incident, a minor injury at the beginning of the case developed over a period of time to where that person utterly had a herniated disk or needed surgery to some body part.
When again at the beginning of the case it seemed they had very minor injuries. Injuries have a way of progressing as time goes on and again to protect yourself. Not only as far as your insurance company is concerned but in terms of any claim you want to make against the other insurance company by all means you should go get checked out.
