What a great idea! Glad that helps some. I don't own any of them, but I do have to use a weird pillow. it's one of those squishy foam things that contours or whatever. I had such nasty neck pain and after using that pillow it never hurts! Well, unless tension happens, but without the pillow it's horrible. Those liberators sound like a good idea. My grandmother and partner had the same thing, the rotator cuff problems. She had surgery and still has pain quite a bit. She had to sleep sitting up because of the discomfort. Too bad she didn't have a liberator! Lol. My partner never did get surgery, but it healed OK or at least it quit bothering him after a couple of years with pain. From what I've witnessed it's a terrible, terrible pain to go through! Sorry you are.
