Morning neck pain with severe headaches

Most mornings I wake with neck pain and severe throbbing headache. Usually, the headache slowly dissipates during the day but on some occasions I'll get several days of unbearable headaches. The neckpain is bearable but the headaches are often so severe I need strong pain medicine. I've tried many different pillows without it helping. This has been happening for about 4 years but there have been period of times when the headaches have not been severe which meant I could exist without pain medicine then. The pain extends into the eyes which feel somewhat out of focus. Pain is most severe around the eyes with a "woosy" sensation behind the forehead. I've been checked for sinus issues and spinal issues.  A bone scan a while ago reported "Mild right C4/5 cervical facet arthropathy" and "mid thoracic spine scoliosis convex to the right" and "mild focal increased uptake anteriorly between the C3/4 and C5/6 vertebral bodies consistent with degenerative change.   A lumbro-sacral spine MRI reported "multilevel disc and facet joint degeneration in the lumbar spine with no significant compressive lesion or abnormality of the conus". An earlier CT scan reported "minor disc bulge L4/5, L5/S1 with a small central disc protrusion at L4/5 with no significant nerual compression. No other lesion seen between L1 and S1" I've been using a CPAP machine for 12 months.
