Do you know how you pulled it? I have been doing a ton of shoulder / upper back work and pre-hab stuff. It has helped me a ton. I still struggle with that area, right now I have a hot spot between my spine and right scapula. Irritating but not as bad as a pulled muscle.
What we think, or what we know, or what we believe, is in the end, of little consequence. The only thing of consequence is what we do. -John Ruskin
