What should i do if misaligned c2 and c3 vertebrae causing severe neck pain?

C2-3 alignment: The first question is understanding what you mean by misalignment. Are we talking about positional alignment, such as described by a chiropractor, or true anatomical subluxation, known as a spondylolisthesis. If the latter, it should be evaluated in light of your symptoms to see if it requires treatment or observation and conservative management.

See neurosurgeon: See neurosurgeon for further workup and surgical stabilization if the malalignment is confirmed to be causing your neck pain.
