RESTCLOUD Neck and Shoulder Relaxer, Cervical Traction Device for TMJ Pain Relief and Cervical Spine Alignment, Chiropractic Pillow Neck Stretcher (Blue)

Non spon but have you tried this? It's only $20

I though I read that you said you have pain down your arm and numbness ear your ear and stiff neck? If so that is caused by your neck. Shoulder injuries can cause you to tense up to try to stop or keep pain from happening, especially while sleeping. I’ve been through a lot of of that. This simple film device works wonders for your neck and releases the vertebrae in your neck. You lay down with it under your neck and slowly move your neck a little to the left the right back-and-forth and you’ll hear the popping of the vertebrae. It worked for me over and over. https://www.amazon.com/Shoulder-Cervical-Traction-Alignment-Chiropractic/dp/B07QSFJ8S2 gentlemen
