Is this a case of racism? Do I even have a case? Unsure about it all.?

I went out one night to a cowboy bar back in January with a few friends and we were there for about 2 1/2 hours and then one of my friends spilled a drink (by accident) and it fell behind the bar, where the bartender's ice and bottles are. The bartender said to her " No one spills a drink in my bar", and the proceeded to call the bouncers to escort her out. The bartender made it seem like we were being reckless and throwing things around, but there were people there that were throwing bottles and gles on the floor. Then one of the bouncers grabbed her and then proceeded to drag her out, and another grabbed her bf, and dragged him out as well. I had the tickets for the coat check for the 3 of us, so I went to grab them, cause it was winter, and we just bought those coats that same day. As I was doing this, the biggest bouncer came up to me and start to grab my arm and was gripping me hard, and I said " I know I have to go, I'm just trying to grab our jackets" and he was like " NO! Get out NOW!" and I said " These belong to us, I'm grabbing them ". Then the lady in the checkout came back with them, and as I was walking out the door he started pushing me and shoving me as though I was resisting, but I wasn't I was going out freely. When we got near the door he push me really hard and I almost fell over, but then I caught myself, and I said " This was racism, we didn't do anything wrong it was an accident" and he called me an "Indian sqaw" then grabbed the back of my shirt and literally threw me out of the bar door then called me "garbage". When he threw me I somehow rolled my ankle and sprained it. I had to be taken to the emergency room, and my ankle was swollen for about 6 weeks, and still swells to this day. Doctor said I had torn ligaments, and it would take a long time to heal. I'm not sure how to go about a Legal case but my husband, said I do have one. I also had to quit university cause I take the bus and I could not walk for weeks, and they said I missed too much to finish, so I had to withdraw for the remainder of the year and apply for retroactive withdrawal. So what I want to know is, do you think I have a case for the damages, pain and suffering, humiliation, and for missing school? I've never been in a situation like this, and am unsure how to go about doing anything really. Any help is greatly appreciated and thanks so much in advanced. :)
