If you can attch any of written MRI reports, those might be better for us to help with.

I guess I have more questions for now..

I see you work from home , so I'm guessing at desk with al lot of phone & computer use?
That can be a factor for neck curvature changes and arm pain.
Weight of head hanging out off of the neck for many hours and years.

Did any PTs or DCs focus on neck/head/shoulder posture?
Did they quiz you each session if things felt better or worse and adjust the treatment if needed?
Or did those feel more like generic cookie cutter PT/DC treatments and not focused on your specific needs?
If they are doing generic protocols vs specific treatments for you it will be much less effective..

Any mention of tight muscles, trigger points, soft tissue etc?
Any past whiplash or head/ shoulder injuries?

Often surgery can take car of mechanical issues, but pain & other symptoms might still remain...

If computer/phone /reading with the forward head & arm postures fits for you, I suggest exploring our TOS forum sticky threads to see if some of it might fit for you..
Trigger point information {TrPs} for short
DOCTORS & PTs List and saved PT info threads

It is possible to have a secondary factor along with the C spine issues..
There is also internal scar tissue that some have more problems with from injuries or surgeries...
