What are the thoughts on chiros?

Lot of guys talk about the impact of years of abuse on their backs and necks from lifting.

Some chiros will talk about how necks being misplaced can effect your nerve function in other areas of your body.

I've had neck and shoulder issues in the past stemming from the way I sleep combined with lifting as well as recently my collar bone was completely out of place lol.

For me, I do feel a pretty big difference after seeing a chiro, but was curious as to others experiences.

Those of you who don't like chiros what do you find is a helpful alternative for neck stuff or spine and shoulder stuff?
