A pain the neck!

I paid a visit to a local chiropractor to have a look see and to determine if he might have insights into my neck pain and headaches. His claim is that my neck is a fair bit out of alignment to normal (the green line). Instead of a nice, single curve - I appear to have a bit of and S-curve. I do have a fair bit of neck pain and headaches and they may very well be cause and effect.

I have some doubts about the chiropractic profession. Folks I know swear by it or swear at it. Anyone with any thoughts, please comment.
