I was in an accident where I was struck by a car. I'm the emergency room they cleaned and stitched some of my wounds but not all of them. They didn't even look for other wounds that I complained about. They also found something (glass) in the soft tissue of my shoulder but did nothing about it, and told me nothing about it. I only found out later when I went back in 2 months later because of pain. It has moved and causing alot of pain and limiting what I can do. What should I do about it all?
