(Concern) Frozen shoulder symptoms

I am in my late 40s and have been experiencing pain in my right shoulder for the past month.

The symptoms feel like slight shoulder stiffness or a sensation similar to not having slept well, and I keep moving my arm even while sitting. Are frozen shoulder symptoms only painful in one shoulder like this?

My left arm is fine enough to do windmill exercises, but specifically my right shoulder, to be precise, when I lift my shoulder, both the front chest and the back feel pain. I don't know if this is a frozen shoulder symptom.

I just thought I was overweight and that everything was creaking here and there, but since it seems to last longer than I expected, if it's a frozen shoulder, I plan to visit the orthopedics department.

Has anyone experienced similar symptoms?
