I had wrist surgery it was the biggest mistake of my life?

I made an operation to the wrist, where they made me a fusion of four corners, and they removed the scaphoid. This surgery was the biggest mistake of my life, I could live with the pain I had, now I have pain all the time, the wrist movement is close to 10%, more than that is always pain. Before surgery I was promised that I would not have any pain, although I would lose 50% of the movement, and that recovery would be between 2 to 5 months. The results I had was pain always, and I lost about 90% of the movement. I’m a cook, obviously I need more wrist movement. My question is what are the solutions to my problem, and if there is any expert who is specialized in this problem. I wonder if there is a possibility of reversing this fusion of four corners.
