I was on a trip to Atlanta and fell on the pathway to take the path train to the car rental area a gentle a airport employee tried helping me up but m

My leg gave up and I felt again I was to embarrassed they want to call the ambulances I said no just to get me up went to hotel where they helped to make me comfortable and but ice on my knee . That was on 10/30/14 ... I report to my dr as soon as I came home he said let's wait and see if it get better in time . I just did and MRI because the pain is getting worst I have a lot of small tears on both sides of the meniscus of my left knee... Can I still file a complain against the airport propriety to pay for my medical expenses
