You make great points about the spine/neck area. I wonder if this is the cause
of such dull, aching shoulder pain, along with the weird nerve sensations? It seems so odd at times. Today, ibuprofen helped. But, I just wish that I could get rid of the feeling of being so "aware" of my left shoulder. There hasn't been one day in the past two months that the left shoulder wasn't on my mind.
I did have an Echo and EKG, along with bloodwork back in May, due to heart palpitations.
