Fear of needles symptoms and conditions

I was on the way to work about 5 months ago and i was rear ended at a stop light. I was a little sore but since I work at a doctors office I signed in as soon as i got to work just to get an x ray of my chest from the seat belt. Thank Jesus I was fine but a a month later I was still having pain in my left shoulder blade. One day at work a provider there saw me rolling my shoulder around as if I was in pain, he offered me an injection repeatedly stating that it would sting for a few seconds and then I'd feel like a new woman. I put aside my EXTREME fear of needles to get the injection because I knew I still had several hours to work. After the injection my back never stopped hurting that night i just tossed and turned. People at work make fun of me because my chair sits almost completely forward but i try to tell them it is my back. well it is now 3 months later and 2 days ago i saw a different provider at my work for depression and anxiety problems. during the end of the visit i made a comment about my back after looking at it one time she had 3 other doctors in there with us all gasping at what they saw. My office manager promised to take care of all of my copays and deductible for plastic surgery and physical therapy to repair the crater in my shoulder blade. But is that enough? I mean to my knowledge they can make it LOOK better but I will always have pain and i can never regain that muscle back...its scary. I mean I'm only 21 years old! Any to all of you I have my "consultation" with my plastic surgeon on the 31st so i will keep you updated and let the ones of you that are curious if it is worth it or not. Thanks for listened.....
