I was shopping in A Supermarket and slipped over on a wet floor, there was no warning signs and I filed a report in the accident book, I was struggling to walk and when I went the hospital A and E I found out I have some ligament damage and I will be unable to walk properly for a while now, how much compensation could I be entitled to for a personal injury like this?
