Recently Diagnosed

So as the title suggest I have been diagnosed with this. Based off reading a lot of people’s experience I know my situation isn’t as dire. I have about 2mm of calcific tendinitis of supraspinatus. My range of motion isn’t as limited but the pain arises when lifting my hand above shoulder to the sky beyond that there is no pain. I tend to stretch my shoulders constantly in an attempt to just reduce or get rid of the calcification but I am also going to PT in where they do massages and electro therapy. Any advice helps but I guess my main question is if I am doing more harm than good by stretching my shoulder?
