I understand the "phobia". Many people are afraid of the type of adjustments that make a "popping" sound. The sound is not the "cracking of bones" as many think but only the gas escaping from within the joint space, a phenonmenon called "cavitation". Most people experience this release as pleasant--not uncomfortable.

However--the even better news is that there are techniques of treating problems such as your that are called "low force" They involve no forceful manipulations at all and the treatments are great for those who feel the way that you do. In fact that is what I prefer myself. One of those techniques is called "activator" and a web site is available with lots of information including a directory of doctors around the country that are qualified in the technique. I would recommend one with an advanced rating.
