Beth, thank-you for writing this story. Don’t forget the fear response to those repressed memories. I have my version of a frozen shoulder and pursue specific yoga asanas to relieve the symptoms.
My go-to is supported Half-Moon. I set my butt against a door frame or the bathroom counter and do both sides. When I hit that pain spot, I ask my breath to ‘breathe into the pain.’ When I’m done I thank my body for helping me. It might not cure you, but it will develop your body awareness, a/k/a interoception or proprioception.
I habitually hitch my right shoulder up when I hear something I don’t like, or start working on something hard. I regularly slept on my right shoulder until the pain prevented it. Anger, fear, shame, rejection, grief, and humiliation are so intertwined it is hard to know which of these feelings is refusing to let go.
Be as patient with your process, as your body has been with you. It has been supporting you all these years. :)
