I dislocated my right shoulder years ago, and that, coupled with multiple rotator cuff injuries makes full back access with my right arm a mere pipe dream! I used to get a very itchy back with great frequency, and I was grateful that my Mom bought me a back scratcher years ago. Also, my fiancé does it for me often. It is SO INSANELY DRY here, and that is a lot of the reason it is necessary, but I also find that my back itchiness seems to vary with hormones. Weird.
Before I injured my shoulder, I could reach most of my back.

It's good to hear it's not just me!
