Compensation

Almost 2 years ago I was out with my husband and my foot slipped on a worn down step. My knee was badly injured and swelles up. I could not bend it or walk on it for almost 2 weeks and had to call in sick to work as it is an active job. So my husband convinced me to claim on one of those no win no fee things. So I started and that, almost 2 years on I am still claiming. I foubd out this morning it will be most probably going to court and bloody regret going through with the claim. We havent been where I had the incident since because i wont go there now but my husband has been to see the step which they have now replaced. but they are denying all knowledge. I never broke it I do have strong bones. Has anyone had this happen before, if so does anyone know what I have to do or any advice?
