Slipped and fell on banannas in a major grocery store

I slpped and fell in a grocery store on bananna's that had been dropped on the floor. The manager took a long time to come and when she did, promptly said that she thought they had cleaned this up. In falling and trying to brace myself I injured the right side of my neck, shoulder and arm. When I left the store I went home however by the next morning I could not move my neck or arm. Going to the emergency rooom the doctor once I told him what happened looked and my back and was able to trace with me saying exactly where, the area that had been affected as it was so swollen. I was given a two types of medicine along with a pain shot and taken off work for a week. I have tried to talk to the stores insurance compnay but they feel since I have insuracne they are not at fault.
