brainstemmed,

There are thousands upon thousands who have been helped with upper cervical chiro. Your situation is unique. My other chiros were far more aggressive with C-1 and C-2 that the NUCCA chiro. If Blair, NUCCA and AtlasOrthogonal were dangerous, they chiros would have a difficult time getting malpractice insurance. Instead, their insurance is substantially less than most MD's. MD's kill 180,000 each year due to mistakes and such.

You either have a unique condition or were treated improperly or both. Often times, problems arise when two separate problems combine.
