It's hard to say really, some chiros are very good and some are not so much.

If they take a comprehensive history and ask many questions about how you are feeling, any previous symptoms and then do a careful evaluation before doing any adjustments, they may be one of the better ones.

But if they just kind of rush you into adjusting and no real assessment and not x rays at the very least, then I'd pass on ones like that..

But with most head or upper body impacts , some things can be knocked out of alignment and so getting them put back in place would be beneficial.
Just be cautious of the ones doing the adjusting, if they seem to rush or be careless avoid those types.
