Get an xray
Christy, it is very difficult to sustain a dislocaion of an elbow in that it takes a signicant impact for that to occur. Rest and ice and support for now.
Avoid an ace wrap as this may cause swelling above or below the elbow. It is very important for you to get an xray of your elbow to get a correct diagnosis. If the xray is abnormal, you need to followup with an orthopaedic surgeon.
