Consider the muscles in your neck between your head and right shoulder.
I’ve been using this visualization technique to help me with stretching my neck, shoulders, back, lower back, and hips. I’ve found that I am better able to “click” things back into position, like I’m my own chiropractor. I imagine that all of the muscles in my body are a series of rubber bands. Sometimes, the rubber band ties itself in a knot, or slips out of position. A common one is in your neck / shoulder area, when a particular muscle should be on top or side of your shoulder socket and switches to the opposite.
You may have already read some of my blog posts on lower back pain and chiropractors. I've found that while a chiropractor can get you out of pain using spinal adjustments, yoga will strengthen your muscles and correct your posture (when done correctly). The first thing you learn about doing yoga is the importance of correct breathing and how it relates to your posture. I've done a bit more reading and it turns out that breathing is much more powerful than many believe.
