I had an xray and an mri for left shoulder pain. Please explain results

Question

MRI: Inferior capsule anteriorly inferiorly in the axillary recess appears to be thickened with surrounding edema. Trace glenohumeral joint fluid extending into the subcoracoid recess.

 It's my non dominant arm/shoulder. I have not ever had shoulder issues prior to this issue (no accident nor surgery) I am  47 years old, a female who works overhead @90 degrees for 8 to 10 hours a day for almost two years now..could this be work related? And is it easy to cure? Will it come back if I continue in the same line of work.

Also xray results say: no fracture or maIalignment is identified. The joint spaces appear maintained. An 8mm calcific opacity interior to the inferior bony glenoid is identified. This may represent loose body or osteophyte.
