Your chiroppractor does not sound like an upper cervical chiropractor.

Did your neurochiropractor spend any specific time with your upper neck? Upper cervical chiropractors will focus on the upper neck with very minor efforts on the rest of the spine. The theory is that if the upper neck is functioning properly, the rest of the spine will be able to settle into correct position. The treatments are not the head twisting, neck bending and neck popping type.

Upper cervical chiropractors will take a very specialized set of x-rays of the neck, especially where it contacts the skull. This is a very difficult area to treat correctly. Even spine/neurosurgeons often miss injuries to this area. X-rays and CT scans do not image the injuries very well.

A chiropractor treating you three times a week for three months sounds more like he was interested in generating income. Common in Work Comp cases. I messed up my back with my concussion and did not have anywhere near that many adjustments.
