My farthing law was hit from behind whilst stationary and his neck and back took the impact, it was me that was pushing him to the doctors, he was saying i'm alright but the doctor discovered serious whiplash and damage to the lower part of the spine, this happened the back end of april since then he's had to go back several times for stronger tablets as he drives for a living so after getting up from great lenghts of time he's stiff and the same in the garden, they said they will review it upto 5 years as back injuries gradually get worse as time goe's on.
Get to the doctors you will have more damage than you think.
