As advised above - depends on many factors .
The compensation for the actual injury itself ( known as 'General Damages' , for pain suffering and loss of amenity ) will also depend on the prognosis - i.e , length of time for recovery to pre accident state , if a full recovery is anticipated , or whether you will be left with permanent symptoms , and if so , the level of those symptoms
Aside from the actual injury itself , you can also claim for what is referred to as ' Special damages ' which are losses suffered or expenses incurred , as a direct result of the injury - things like loss of earnings / treatment costs / travelling expenses to medical appointments , to name a few .
Another important factor as to how much you receive , will also depends on how robust your representatives are in pursuing your claim , against the other party or their insurers .
I trust the above is of assistance
