I have had a cervical fusion as well, and all the above info is good. Before the surgery I could not use my arm at all. The neurosurgeon was going to fuse two levels but ended up fusing only one, the other is stil bulging. It took some months to get the use of my arm back. I think about 6 months or so, and that was one level. So give yourself some time. There is good advice in the above posts, and there is hope.
