Did your doctors or therapists consider Thoracic Outlet Syndrome? I've struggled with severe pain in shoulders, arms, hands and fingers for several years. It was sort of discovered by accident. They removed both of my first ribs (rib resection) and in combination with a Kinesis keyboard and a Wacom pen and tablet as a mouse replacement it's much better now.
Unfortunately, the solution came a bit late. The strain on my nerves and blood vessels caused by the thoracic outlet syndrome has damaged my arm nerves. And after the second rib resection, the one on the left side, my plexus brachialis got severely damaged. It took nearly 2 years to partially recover. My left arm gets tired very fast in certain positions, my left thumb is partially numb and sleeping on my left shoulder can be painful.
I can't image how much worse it would be without my Kinesis Advantage keyboard and my Wacom Bamboo tablet. Using another computer or laptop with an normal keyboard, touchpad or mouse, is hell. An iPad Pro with a pencil (and a tablet stand to hold the tablet) is much better.
