What Causes Extreme Arm And Shoulder Pain Post A Gardasil Shot?

Hi, I received the second Gardasil needle over a month ago and I am still in excrutiating pain. I can now move my arm about half way up but it is still very painful. My shoulder is killing me, to the point that I am starting to feel depressed because I am always in pain and not sleeping well. The doctor gave me mylan-cyclobenzaprine,for at night, ketorolac, 3 to 4 times a day and ratio-lenoltec #3. I have been on all of these three médications for a month now. They send me for an ultra sound and the results were negative. Is it possible that he put air in my shoulder? Maybe he forgot to take out the air? I am at a loss and losing my mind. It is affecting my day to day tasks because it is taking me way longer to do everything. Any advice would be greatly appreciated. Some people are telling me to get a lawyer but I don t really care to make money off this I just want the pain gone. Please send me some advice.
