I Bumped My Elbow Hard On A Door. I Went

I bumped my elbow hard on a door. I went to the emergency room; no fracture. However I have a bump filled with fluid (small to medium size). When I touch it (squeeze it), I feel like a small ligament moving or tiny tendon. Should I see an orthopedic to remove the fluid, or should I just apply ice to the bump and not worry about it?
