My shoulder dislocated while dancing, but went back right in and now it is numb. Please help.

Hello doctor,

I am a 38 year old female. My height is 5 feet and 9 inches, and I weigh 130 lbs. I am a professional dancer. I dislocated my left shoulder while dancing. I had to make a move that involved throwing the arms out and across the body to the right side sharply and quickly. It popped out for about two to three seconds and went right back in. It was sore for the first two days. Initially, I wore a swing and then began moving it gently through a full range of motion. I had slight pain when rotating it outwards with my arm at 90 degrees and lifting up with arm straight out to the side. It has since been 11 days since the injury and the pain has completely subsided. However, I am now experiencing periods of numbness along a line down the center of my shoulder toward my elbow. I am wondering if it might just be a nerve swelling because I went back to activity too soon or if I should be concerned that the shoulder went back in and is compressing a nerve. Or is it something else entirely? Should I give it more time to rest or get to a doctor to have it evaluated? Any opinion or advice would be great.
