shoulder blade pain

I had a tingling pain that lasted for a week, from my shoulder down to my shoulder blade. It wasn't bothersome when I was still, but as soon as I started moving or slung my bag to my side, the pain was excruciating, from my shoulder down to my shoulder blade. I eventually decided to try physical therapy and went to Leaders Internal Medicine in Doma-dong. The warm compresses, physical therapy, and electrotherapy were surprisingly helpful. As I continued going, the pain subsided, and now it's gone.
