Don't have frozen shoulder but am dealing with similar pain. Long story short: had lymph nodes removed in March, nerve damage in left arm, arm immobile, developed lymphedema (can't have shots in the arm), currently in painful PT. Able to move arm and fingers now but can't raise arm above my head yet (unless I'm lying down) ... I just want to be able to groom my hair properly :( how vain is that ??? Therapist predicts 90% movement by end of month. Hope she is right.
