rolled a car maybe 15+ years ago damaged a disk or two in lower back, went to chiro he did 1 or 2 pops then I followed it up with an hour massage from a chick and combo of that had me feeling good for many months, did that combo a few times over the years whenever lower back would start to tighten and now doesn't hurt as bad or get tight like it used to so don't go anymore.
On the flipside my dad had some problems went and saw a different guy got popped and made him worse.
