So, I choose my default dancing icon here because I can actually raise my right arm over my head again. My frozen shoulder has now thawed enough to allow almost anything.
Tonight I had another massage, and we worked on the shoulders and a lot on the neck. Playing tennis yesterday (for the first time in a year!) really got to my neck, for whatever reason.
I'm hopeful that by the end of the summer I'll have my complete range of motion back. And I hope I'll also have something of a forehand (not that I ever had much of one).
