I got "nudged" in the rear a few years ago. I was at the front and there was about 3 cars waiting behind me when a lorry went into the back of us. Very small scratch on the bumper but i did feel something so went to the doctors that day.
Claimed thru my work van insurance as was driving their car. Always had a bit of a back problem so when offered Chiropractor or whatever its called i went with that for 10 sessions. Really did help. Then after a few years got made a couple of offers and i accepted the 2nd offer.1st offer was about £1200 the 2nd offer which i took was £2500. Back is better tho i still wish i had those chiropractor sessions still paid for as like to carry on with them!
