Ow, my Arm!

Have I mentioned that I have a torn rotator cuff? All that rest did was give me a frozen shoulder, or at least extremely restricted range of motion in that arm. The doctor has now ordered Physical Therapy. Through effort and a lot of pain I have almost completely restored lateral and forward arm movement, although not using it for a few hours decreases that range again. But I am having real trouble with placing my hand on my back, as if to hook my brassiere. Hope the PT helps!
