IMO, chiropractors are useless. I went to a few, had adjustments, neck cracked and all the other nonsensical 'procedures'. Long story short, I ended up with the same pain I had (nasty upper shoulder blade pain) when I initially started.
I decided to go to a really good masseuse (strong Asian chick) and got unbelievable relief on a one and only one 20 minute deep tissue massage.
That as about a year ago. Never had to go back.

I did NOT have a nerve issue, though. I'm just saying I don't believe in chiropractors.
