Is it possible to treat shoulder issues with acupuncture?

Since a year ago, I have been experiencing severe pain in my shoulders and back. The shoulder pain was especially intense. When it was very bad, I couldn't even rotate my arm due to the pain.

I have been continuously visiting the orthopedic department for treatment, and they said there are no major issues on the X-ray, so since then I have only been receiving physical therapy and manual therapy.

When receiving treatment, I feel a bit better and less pain, but after a few days, I return to my original condition and start hurting again.

According to what I heard, acupuncture is not very effective for shoulder pain, so I didn't visit a traditional Korean medicine hospital, but now I'm worried. The exact area is around the left shoulder, and when I move my shoulder or lie down at an angle on that side, the pain becomes severe. In some cases, even slight movement causes pain.

I wonder if these pains can be treated with acupuncture or other traditional Korean medicine therapies...ㅠㅠ
