Hi, Fairy tale! Well, I have just gone through the frozen shoulder routine and have corrected the situation with no medication. I couldn't lift my arm either. Getting dressed was a trick and holding a hair blower was unbelievable. I couldn't put dishes in the cupboards, couldn't reach without pain that could bring me to my knees. I couldn't reach behind my back either.
My doctor sent me to a physical therapist and she helped me with some exercises I could do to help bring more range of motion back to my shoulder. This did help.
I have fibromyalgia, another chronic pain problem, that deals with muscles, tendons, and ligaments. I will get pain in places and have found that much of the pain is referred pain. So I bought a book called The Trigger Point Therapy Workbook that I found on Amazon and it is fantastic! It shows were the trigger points are and you can massage those areas and it relieves pain.
So, I got out that book and looked up rotor cuff to see where the trigger points were for this area. You see, you have muscles going from your back, your shoulder blade, your neck, and your chest wall...all feeding into the shoulder. The physical therapist showed me this. Anyway, in the book it showed the trigger points that can affect the shoulder and I started massaging those areas and now I have almost complete range of motion back!
I see a neuromuscular massage therapist and she taught me how to get to those trigger points. You will know when you have found them because if you press on them, it will be very tender. What you do is you press as hard on the trigger point as you can stand. Then you massage it for a few seconds and then press again. This helps loosen the muscle knots and smoothes the muscle so it relieves pain. Keep doing this until the trigger point doesn't hurt nearly as much and then move to the next area. This really does work.
I had a terrible pain in my side one night and couldn't stand the pain. I got up, checked where the trigger points were for that area and they actually were running along my spine. I live alone so I got my tennis ball and leaned against it on the wall. I found the tender areas, pressed into the ball, then moved slightly to simulate massage. I did this for several minutes and the side pain improved immensely...enough that I could go back to bed and go to sleep! The next morning my side didn't hurt at all. So it does work.
So you might want to check out that book. Amazon lets you read the first few chapters so you will get an idea about the book. It's not expensive either...around $16. I did show the book to my physical therapist, she loved it, and ordered her own copy!
Here is a good link from the Mayo Clinic about a frozen shoulder.
