The treatment is primarily a self treatment. Some very gentle PT or chiro or osteopathic therapy may help but the most important therapy is discipline with sleeping and resting posture. I also had to lower my computer monitor so I was not tipping my head back to use the bottom of my trifocal glasses.

Avoiding the vertical forces is also helpful. Shoulders and head forward when the road gets bumpy can help.

I also live with anti-inflammatory meds. Either aspirin (enteric form) or ibuprofen. Been taking it for more than a decade. Omega 3 fish oil and curcumin concentrate have anti-inflammatory value, too.
