Things seem to be progressing very well with with the ROM in my left arm. I am able to reach the back of my head, which is far better than what the surgeon had set as a goal for me by my appointment on 09.18.17. Rotation of my left arm now matches that of my right arm and there is zero discomfort or tightness with that movement. I have another 12 days before my next follow up appointment and I hope to have ROM that matches in both arms by then.
I'm being smart and taking it slow by not forcing the ROM and by wearing my brace as instructed.
