tripple neck fusion c4 to c7

April of this year i had a level three neck fusion. I had a bad disc and very bad spinal stenosis ( sorry about the spelling)
The moment i woke from surgery i was in horrible muscle pain from both sides of my neck down to my shoulders. I was told that this was normal and it would go away. So here we are 6 monthes later and the pain i had before the surgery is gone, however the constant muscle spasms i live with daily is worse than the pain i had before. I have had a post surgery M.R.I. and was told that " What a great looking fusion! Your fine!"   BUT I AM NOT FINE!!!!   In fact , i would say that this pain is worse and more frequent than the pain i had before the fusion. I am so damn aggravated. All i am getting from the doctors is that i am fine and shouldnt be in pain. What do i do!????
