Its nothing to worry about the swelling. If hou have pain then can suggest fir better treatment optikns, but you dont have any symptoms of soft tissues or bone issues, i would like to suggest you to do shoulder and neck stretching exercises. Through shoulder exercises the swelling will be reduced and also apply hot pack twice a day, this will also help in reducing swelling.
