Head & Neck Pain Right Side Base of Skull

I have been suffering from constant head/neck pain for over 10 years.  The pain begins behind the ear, right side above the base of the skull.  It radiates down the spine below the shoulder blades.  I have had the following treatments:  cervical spine fusion c5/c6 due to rupture disk, botox injections to the head, neurostimulater implant 4 yrs then removed, steroid injections, and taken huge quantities of narcotic pain relievers.  I have stopped taking the pain relievers due to the side effects and now live in constant pain.  The only relief that I can get at all is by putting pressure on the area that hurts and the pain comes back immediately upon removing the pressure.  Any help that you can offer will be appreciated as the doctors are at a stalled point and we need some fresh ideas.  Thank you for your help.
