So, evidently, I have frozen shoulder.

[Grasswire2]

i had a badly aimed flu shot in November, and some discomfort although I knew how important it is to keep it moving.

Then, in April, I had a pacemaker implanted and instructions were to keep use of that left arm to a minimum (while also attempting to avoid frozen shoulder)

It's worse. I have to accommodate it constantly with the way I move, to try to avoid pain.

I guess I'll have to go for physical therapy.
