(Concern) Shoulder pain

These days, I'm worried about my shoulder.

There is impingement syndrome caused by multidirectional shoulder instability.

I have been doing rehabilitation exercises recently, but I think something was not right.

My shoulder hurts so much that I am not doing any exercise right now.

The ultrasound suggests a suspicion of partial tear.

Is there no answer other than an injection... It's frustrating.

I am trying to minimize the use of my shoulders as much as possible.

I'm feeling frustrated about what I should do..
