Left shoulder frozen shoulder pain management - stretching

Several years ago, I went to the hospital for right shoulder pain and had a rotator cuff partial tear injection and physical therapy. When there was little improvement, I underwent laparoscopic surgery. Since last year, my left shoulder started hurting again, so I went to the same hospital, and this time I was told it was frozen shoulder. I had similar pain in the same area and a similar range of motion, but the diagnosis was different. I think stretching is the most important for frozen shoulder. Even when it hurt, I endured it and did it steadily once or twice a day within a tolerable range, and these days, the pain has significantly decreased.

These days, there are many videos on YouTube, so it's really easy to follow along.
