I had cervical fusion 3 weeks ago. The pain I'm having from this seems to be more than when I had lumbar fusion last summer. I have just recently developed muscle spasms in my right shoulder is this normal. Also how long does it take to actually begin to feel better? Lots of stiffness in the neack and some headaches. Today I had some numbness in my arms and hands while I was doing something is it normal to still have this problem? Please help any advice would be greatly appreciated.
