How much compensation can I claim for a dislocated shoulder injury from a road traffic accident?

[Franny]

I was in a car crash that was not my fault, I was hit from the rear by a drunk driver and they fled the scene without sharing details, can I still claim compensation for my injuries?
I went to hospital and I have injured my back and neck and suffered a dislocated shoulder from the road traffic accident, how much compensation could I be entitled to?
