The bluish color of the area may be due to extravassation of blood under the skin during injection.If there is pain and swelling please apply ice 2-3 times a day and see if the pain or swelling subsides and you feel fine then the color will return back to normal in few days but if the pain increases please consult your doctor he will give you medicines to recover.
