Go get it on medical record, go and have x-rays , whiplash don't allways cause pain straight away , it can come on weeks later . I've been involved in 3 rta and after the first 1 the pain wasn't too bad to start with. A few weeks later the pain was so bad I was on the verge of suicide, I ended up having neck operations , just don't ignore it you minght have no pain or slight pain at moment but go get it checked out . As for making a claim find your own solictor , don't use 1 that the insurance company minght get you to use , if you do decide to make a claim keep all records of appointments attended, any expenses for pain relief tablets/creams , any physio appointments , time off work , any hobbies intrest that have been effected, any expenses if you have had to have work done which you would normally do yourself like cutting grass, decorating ECT . Whiplash if genuine can be bad .
