Shoulder arthroscopy
Shoulder pain or arthritis. I would recommend that you see your family doctor to evaluate your arm. This condition can occur without a prior cause, but is most often due to lack of use related to a previous injury such as tendinitis, bursitis, stroke, etc. Treatment is physical therapy and possibly corticosteroid injection. Plain Xrays or an MRI can be used to evaluate for other causes, but are not needed for the diagnosis of frozen shoulder.
I hope this has been helpul.
