Gabrielle's medical care for an injury

I am a professional organist, harpist and pianist. However, my work is part-time at a church and free-lance, and I therefore don't have health insurance. I, unfortunately, fell on the stairs at my house last week and injured my shoulder, and my left arm is partially immobile. I have Holy Week services coming up for which I need full mobility of my arm to play the organ. I can't afford to go to my doctor, who could refer me to physical therapy. I also can't afford physical therapy sessions.
