I had two rounds of neck injections which only lasted 2 weeks at a time. One week ago my shoulder recovered about 75 % motion range. I saw my doctor who said to just keep up my exercises at home at my own pace. He said it takes 7 months for the arm to heal after rotator cuff surgery. I’m still hurting and unable to straight arm raise more than about ear level, but this is a huge improvement over where I was 2 weeks ago. I told him how many people are posting extreme suffering after this surgery and he seemed surprised. He said true frozen shoulder lasts about a year and a half. He said exercises from now on will be needed to regain range and retain it. The one thing that helped me the most was my tens machine that I kept on with moving the patches around to get movement in those muscles. I slept with it on for more than 4 weeks. Otherwise I don’t think it would have loosened up.
