This guy's story is a good example of how important myofascial release(trigger point work) is. He even thought he might have TOS, but it just turned out to be trigger points in his upper back.
I've been doing trigger point work daily on my entire body. My tool of choice is a Thera Cane. I prefer that over a tennis ball or foam roller, but whatever gets the job done.
