@tfproxy @Antifreeze honestly, chiro is largely bullshit and a bad chiropractor can actually hurt you. Yoga will help your back. I totally feel your pain with regards to the stuff (sitting at work all day is real bad for your back) but try running a few sun salutes and see if that helps before you try chiro. There's lots of pretty decent free videos online with the whole sun salute routine.
@tfproxy @Antifreeze yoga certainly won't cure a bunch of stuff but what it is good for is developing core strength. If your core is good, there's way better support for your back. The kinds of exercises physical therapists prescribe for folks w/ back pain are essentially yoga.
