Adjust? You're only popping fluid out of the disks.
In my many years of experience, only very few chiropractors are competent... most are voodoo practitioners. They snap your neck and spine and they/you perceived something got fixed.
Your spine and neck is self adjusting. Non-traumatic soft tissue injuries/discomforts heal 99% of the time without any medical attention, intervention or medication.
Deep tissue massage from a competent masseuse is 100% better and more effective than those bone crackers.
