How do you politely tell your attorney you'd like him to get busy on your case?

Finally!! I hit the six week mark past my third and final shoulder surgery. I have almost full range of motion and am virtually pain free! My family was involved in a car accident when a young man slammed into the back of our vehicle on the interstate. It took three surgeons to finally "fix the problem," and I am ready to move forward now and put this fiasco behind me. The first surgeon repaired my labrum, the second surgeon did (in his words) "a major clean up job" of inflamed tissue, but he didn't seek out the source of WHY THE TISSUE WAS INFLAMED, and the final surgeon figured out (without any imaging test) that my AC joint was damaged, thus causing more fraying of tissue and inflammation. Oh! He also discovered a nice sized tear in my rotator cuff that was somehow missed previously. I have never had any issues with my shoulders...no health issues at all really besides childbirth. My husband and I collected all of my medical bills and prescription bills, and hand delivered them to the attorney in large stacks repeatedly throughout this ordeal. We haven't pressured him for the past year since he took my case. The accident took place nine months prior to our hiring him. I finally received a letter yesterday from his office stating that he was NOW in the process of meeting with my three surgeons and requesting letters from them. He says it will most likely be another year before we see any resolution. OMG! Really??!! We have picked up every doent this man has requested, done all of our own "leg work," and he is only NOW beginning to do his job? What else can I do to help myself at this point. We have medical bills that we are still paying on; we need to finish this case now. Any suggestions? I don't want to make the man angry and hurt my case, but at the same time, my husband and I feel this case could/should be so much further along at this point.
