Pain at the connection point of the arm and shoulder

I went to the hospital because I had pain in the connection area of my arm and shoulder.

I was diagnosed with a small amount of water and calcification through ultrasound, and I received about five sessions of physical therapy and extracorporeal shock wave therapy.

This doesn't really have any particular effect.

My shoulder doesn't hurt when it's still, but it hurts when I lie on that side or touch it.

It's not that I'm in severe pain or that the treatment is going well, so I haven't been to the hospital.

Is it okay to leave this as it is?

Or is there a good effect from exercises or injections?
