Is chiropractic worth it?

[prof_porn]

I have back trouble. Nothing too major, I'm a young man, but an irritation. Its probably a result of poor posture and sports with poor technique. This includes boxing and cricket.

Basically, I have constant irritation-like a tightness-in my middle back, and exercises to stretch the muscles/spine dont have any lasting impact/benefit. I was pondering chiro.

Any one have any experiences of it? Is it worth it?

Thanks,
