Last December 2013, I fell hard on my knee, stomach and wrist in a local bar. I had not had a drink yet. It was a poorly lighted area with a step up. I had a contusion to my knee according to the ER doc on the following day. Since then they have redesigned this bar , I have not been back to look , I was told this by another person. Besides them paying for my co-pay 9Or the full bill?) as I am insured can I charge them for anything else. I know that knee injuries sometimes evolve over time as I had an injury to my other knee and never received compensation.
