Hi and welcome
I had 4 level cervical fusion done in 05. And they are fine. Everything else around, above, and below, has gone down the toilet. I haven't had a MRI done in several years, my PMs and PTs have told me what's going on just from my telling (complaining?)

I have a constant dull ache at C1&2 sometimes with a low grade headache. I have khyphosis, scoliosis, radicuopathy and osteophytes. A sharp burning pain at T1 and down a few. The NS who did the laminectomey botched it, and left me with permanent nerve damage in my right arm. Makes insect bites real interesting!

All of that came from the fusion, and the lami before it. And it probably has more to do with my former job than anything else, but there may be lumbar surgery in my future too.

Because of that job, I was extremely limited in pain meds. I do Botox injections, PRN.

Good Luck
