Glad you have a knowledgeable doctor. Movement is SO important. Ever since I did PT when I was in a wheelchair...I now do a lot of the seated exercises where I move my foot and hands without even thinking about it. Sometimes I forget to move my hands when I am holding something...and that results in so much pain after a while. I was doing a walk through with our district manager once at work and I was holding a notepad to take notes. My fingers locked in their position while we were walking and I was in tears by the end of it...could not uncurl my fingers and the pain was awful! So yes...definitely HAVE to move the affected limb/limbs. I also take warm baths with Epsom salts when I can because that also helps. Before my current shoulder issues I was taking a bath at least once a day...sometimes twice on bad days...and that is one of the treatments that I am missing the most right now. I hope that things get better for you and that you get the relief you need soon.
