One year ago I injured my shoulder. My doctor took an x-ray and prescribed advil and physical therapy. I did the physical therapy for two months under supervision, then continued the exercises on my own. While I have had some improvement I still cannot perform everyday movement such as putting a dish up on a shelf or washing with a washcloth under my opposite armpit. Should I ask for a more detailed imaging such as MRI because it seems something is radically wrong that the x-ray didn't show and the therapy didn't help?
