Frozen shoulder symptoms

Recently, my right shoulder has been unable to lift properly for no reason.

Maybe I slept poorly at first.

Or maybe I just pressed down while tossing and turning, so I thought it would get better in a day or two, but now it's been almost 2 to 3 weeks, and I still can't lift my arm naturally.

And what concerns me more is that when I raise my right arm, I feel pain above my right chest.

So, pressing on the chest and raising the arm makes it a little easier to lift the arm.

They kept talking about frozen shoulder on TV, and I thought it was just for older ladies and gentlemen, but it seems I overlooked the fact that I am getting older.

I'm actively trying to stretch and move, but will this naturally get better over time?
