I've similar issues ..However I've also narrowing of the cartoid arteries up front of neck & having spoken to neurosurgeon need to see a vascular surgeon. I thought the pain radiating under collar bone & up left side of ear was related to neck issues, it wasn't. I've also pulsating tinnitus caused by the narrowing of said arteries. All discs gone in neck with osteophytes & encroachment of nerves .Anterior cord contour deformity which is responsible for the pain numbness & not been able to hold head up properly..in the meantime lumbar dics have gone with Stenosis, if it's not one thing it's another. Plus due to narrowing plays havoc with my blood pressure, turn my neck it goes through the roof then stables when facing forwards, like yourself Steroid injections offered but declined had 3 prior that hadn't worked so just get on until I can no longer control bladder/bowels then neurosurgeon will operate mmmm .
