I am worried about getting paralyzed from the chiropractor? Is this common?

Common-No. Possible, yes. Stay with experienced chiropractors if you are going to go. When working on your neck, make sure they do not due maneuvers where they pop your neck with your neck extended, as this can lead to vertebral artery dissection rarely. Also, if you already have a herniated disc, over exuberant corrections can be troublesome. Otherwise, know chiropractors are safe and can be great!
