How long until i don't feel pain from a pneumonectomy?

Three to six weeks.: The pain will decrease each week as healing takes place. The is mostly from the muscles in between the ribs being stretched. In some cases a small piece of bone or cartilage may have to be removed to create a window for the instrumentation to to be introduced and manipulated through. Use a pillow to hug it and thus support the rib cage when you are doing your breathing exercises. This will help.
