Easly symptoms and conditions

I got the Kenalog shot in Oct. 07 for my allergies. The nurse gave me the shot in my arm, in my muscle none the less. I now have a large indention in my arm and my muscle is gone. I used to be able to lift 120lbs easily but now I am lucky if I can do 60 without my arm hurting really bad. When you push in on my arm where they gave me the shot you feel my bone. I'm scared that the rest of my muscle will deteriorate. Can someone please tell me what I can do to stop this. Its really scaring me cause I have a little girl that I can barely carry now. thank you.
