Thanks for the responses! I worked with a chiropractor for the last three months and it has helped somewhat. He gave specific exercises for me to try, which have improved my posture and strengthened my back/arm/shoulder muscles. I notice the pain/itch more when I spend too much time with my head forward (phone, computer). FYI, prior to the chiropractor, I tried physical therapy and acupuncture, neither of which helped. Topical lotions have not helped either. I originally thought it was due to nerve impingement, but I had an MRI and CT, and there was none. For me, it's all about posture and exercise. I also got a standing desk, since it also flares up if I sit too long.
